[Q] Titanium Backup restore on JB

I just upgraded my Galaxy Note N7000 from 4.0.3 ICS to 4.1.2 JB (both stock roms), but when I try to restore my apps and data, Titanium says that the folder is empty and don't recognize my backup.

I restored my phone successfully many times between ICS roms, but now I'm getting this problem.

I've tried to re-install Titanium, tried to change the folder location, restart my phone, use stock and custom kernels, and I'm not able to restore my apps and data. When I wipe my phone and go back to stock ICS, Titanium recognize and restore all my data and apps without a problem.

What can I do?

Thanks
