I'm running 5.1. - I'm not sure if I need to post this here or not. I just ran an update on Titanium Backup. It said update unsuccessfull. I tried to manually do a backup and nothing would happen. Again, have I unknowingly changed something to where this won't work? My sd card also shows no updates. should I download the pro version? My backups worked when I was on autonooter, so I think I kind of have an idea of what to do.
