System crash. Had to restart. Can't open eM Client now... How to solve the problem?

What can I do to start eM Client again?

After a system crash I had to reboot…
Now, when I try to start eM Client, I receive this report:

System.Data.SQLite.SQLiteException: Some kind of disk I/O error occurred
disk I/O error (main/4C8)
