Database is locked

I was moving an email from inbox to another folder, and it froze. So I closed and I get a database check box that goes on forever and it wont’ open when finished. How can I get this open now?

Here is the text from the database text box:

System.Data.SQLite.SQLiteException (0x80004005): database is locked
database is locked
   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 MailClient.Storage.Data.DataStore.GetConnection(String relativeName)
   at DbRepair.CorruptionChecker.CheckCorruption()
   at DbRepair.FormCheck.Check(Object state)

I would suggest that you close eM Client. You might need to right click on icon in toolbar to close. I would then close All apps and shutdown your computer.
After you reboot I would hope that you no longer have this trouble.
