Titanium Backup doesn't recognize backed up files

Completely wiped my g4, backed up app data + system data prior the wipe.
Now, I open titanium backup, went on to 'backup folder' in preferences, I can see all of the backed up files in there, but when I go to 'Batch' and then 'Restore' it shows 0 apps to restore. clicking on 'reload application' didnt help, also tried re-installing.

what else can I do ? :(
