computer crash. Reinstallation issues

my computer crashed. I had all the files backed up and have restored them to their original location. How do I get em client to recognize the files? I have an em sync account. How do I activate that again?

You shouldn’t need to do everything, if you back-up the whole database folder and copy it back to the correct location. Unless you have mess around the the database location settings.

C:\Users%Current User%\AppData\Roaming\eM Client (Vista/Win7)
C:\Documents and Settings%Current User%\Application Data\eM Client (XP)
