Hi @panthernet, can you paste your stacktrace?

Here you go

   at LiteDB.DictionaryExtensions.<ParseKeyValue>g__ReadValue|2_1(<>c__DisplayClass2_0& )
   at LiteDB.DictionaryExtensions.ParseKeyValue(IDictionary`2 dict, String connectionString)
   at LiteDB.ConnectionString..ctor(String connectionString)
   at LiteDB.LiteDatabase..ctor(String connectionString, BsonMapper mapper)
   at X.DB.DBManager.<Session>d__1.MoveNext() in D:\Projects\x\x\Classes\DB\DBManager.cs:line 86

And this is for the ticks exception

   at System.DateTime..ctor(Int64 ticks, DateTimeKind kind)
   at LiteDB.BufferSliceExtensions.ReadDateTime(BufferSlice buffer, Int32 offset)
   at LiteDB.Engine.HeaderPage..ctor(PageBuffer buffer)

   at LiteDB.LiteDatabase..ctor(String connectionString, BsonMapper mapper)
   at X.DB.DBManager.<Session>d__1.MoveNext() in D:\Projects\x\x\Classes\DB\DBManager.cs:line 86

same error here

I get this error when using a connection string. I did what the document says, and i get this error: System.IndexOutOfRangeException: 'Index was outside the bounds of the array.'

This exception was originally thrown at this call stack:
	LiteDB.DictionaryExtensions.ParseKeyValue.__ReadValue|2_1(ref LiteDB.DictionaryExtensions.<>c__DisplayClass2_0)
	LiteDB.DictionaryExtensions.ParseKeyValue(System.Collections.Generic.IDictionary<string, string>, string)
	LiteDB.ConnectionString.ConnectionString(string)
	LiteDB.LiteRepository.LiteRepository(string, LiteDB.BsonMapper)
    SampleForm.Form1.Form1_Load(object, System.EventArgs) in Form1.cs
	System.Windows.Forms.Form.OnLoad(System.EventArgs)

    using (var db = new LiteDatabase(System.Configuration.ConfigurationManager.ConnectionStrings["LiteDB"].ConnectionString)) { ... }

Ok, I found a bug in ConnectionString parser, when finalize with '. I'm fixing.... for now, just remove open/close '

Got the same error:

My DB does not have any passwords set.

@alex-fomin Could you provide your datafile and the connection string you're using?

The datafile is pretty big (73Mb): https://www.dropbox.com/s/5agkno8ikr2mb2t/ProcessingQueue.db?dl=0
Connection string is just "ProcessingQueue.db"

@alex-fomin The file you sent appears to be a SQLite datafile.

I believe the same issue is with $ character. While interpolating some strings I mistyped the name of the DB and got the same error.
Oh, and in my case, I have no password on the DB.

System.ArgumentOutOfRangeException: Ticks must be between DateTime.MinValue.Ticks and DateTime.MaxValue.Ticks.
Parameter name: ticks
   at System.DateTime..ctor(Int64 ticks, DateTimeKind kind)
   at LiteDB.BufferSliceExtensions.ReadDateTime(BufferSlice buffer, Int32 offset)
   at LiteDB.Engine.LiteEngine..ctor(EngineSettings settings)
   at LiteDB.ConnectionString.CreateEngine()

I have a similar scenario.

System.ArgumentOutOfRangeException: Ticks must be between DateTime.MinValue.Ticks and DateTime.MaxValue.Ticks.
Parameter name: ticks
at System.DateTime..ctor(Int64 ticks, DateTimeKind kind)
at LiteDB.BufferSliceExtensions.ReadDateTime(BufferSlice buffer, Int32 offset)

DB is located in C:\Users<username>\AppData\Roaming<publisher><feature>\Autosave.db
DB is password protected - 16 characters, Alpha-Numerics only - upper and lower case.
DB connection mode is shared.
The full connection string is: (Identifiers removed - but can guarantee there are no unusual characters or symbols at all)
Filename=C:\users<username>\appdata\roaming<publisher><feature>\autosave.db;Password=;Connection=shared
No surrounding quotation marks, no internal quotation marks, symbols, irregular characters etc.
The Connection string works fine on over 100 user machines since the version was released containing LiteDb a week ago.

The user in question installed the application, and on the first-run - the DB was generated, not long after opening the app, the app performs a GetAll on a collection in the DB - the GetAll call triggered the exception.

I have a copy of the DB and I get the same issue if I try to use my app to access the data.
I also get the issue if I try to connect to the DB using LiteDb Studio.

For the user - deleting the DB that was originally created and letting the app create a new one resolved the issue.
@lbnascimento - would the db be helpful to you at all in debugging the issue?

I have the same problem described by @alex-nicholas
Is there a solution?
