Hi all.

I'm having a problem with switching databases. I suddenly cannot access one of them. An error (E1) popped up at first. On retrying to switch and on the program's advice I tried to restore the DB, but got an error (E2). I'm pasting the errors I got. I would appreciate some help or advice in what to do to get back access to the DB. If you require more information do ask. At the moment I have no idea what information would be useful to you people.

regards,
plusunim
