It's as though the update software is looking to make sure things are just as they are supposed to be. I wonder if those who only "froze" apps are able to update, and we who uninstalled apps are not able to update; because many of us may not have had Titanium settings correct? I noticed that in the "Preferences" menu, there is a selection called "Restore Backups to....". Mine was set to "Default location(chosen by Android). The second choice: "Original location" might be a better choice. Just thinking....it may not help. I still have a copy of my original Titanium backup on a spare SD card....made this before I changed anything.
