It would help if you provided the error messages you get with the gui in 
the logs...
However, my guess is that the userid/groupid for the new install doesn't 
match the old. You have two choices:
1) Uninstall backuppc, remove the user/group backuppc, manually create 
the user/group backuppc but make sure you match the userid/groupid on 
the files in /var/lib/backuppc....
2) Re-mount /var/lib/backuppc and map all existing files to the new 
userid/groupid that the backuppc user has.

Another possibility, you need to re-create the config files and/or hosts 
file.... The contents probably don't matter a lot, as long as the 
hostnames match the old ones (see /var/lib/backuppc/pc/ for the right 
names).

Hope that helps....

Adam
