Problem with thunderbird
 

I am on Kubuntu gutsy. My thunderbird was working fine until I copied a backup "local folders" directory into the profile, unfortunately without keeping a backup of the original, and now I get no mail. I tried uninstalling and reinstalling but still no mail. I think I will have to totally remove all directories attached to thunderbird and start over, but I am not sure this is correct, and whether something will break if I do it. Could anyone help?

So, did you copy a directory from a prior thunderbird instance?
