Database corrupted-Help-Quick-Please

I get the following error message when I try to start eM Client:

System.Data.SQLite.SQLiteException: Attempt to write a read-only database
attempt to write a readonly database
at System.Data.SQLite.SQLite3.Reset(SQLiteStatement stmt)
at System.Data.SQLite.SQLite3.Step(SQLiteStatement stmt)
at System.Data.SQLite.SQLiteDataReader.NextResult()
at System.Data.SQLite.SQLiteDataReader…ctor(SQLiteCommand cmd, CommandBehavior behave)
at System.Data.SQLite.SQLiteCommand.ExecuteReader(CommandBehavior behavior)
at System.Data.SQLite.SQLiteCommand.ExecuteNonQuery()
at System.Data.SQLite.SQLiteConnection.Open()
at DbRepair.DbTools.OpenConnection(String fileName)
at DbRepair.Form1.CheckCorruption()
at DbRepair.Form1.Check(Object state)


this does not look like corrupted database but more like that some other program is accessing it.

Can you please check if any other software (3rd party backup tool, antivirus, etc…) is not touching into database?
