I seem to have not included the modified email app stock in this version, but you should be able to download it from the modified apps in the UD settings.
How exactlly do you download the modified apps? I clicked on it installed it but the problem still happens
Try this cody:
Restore your advanced nandroid backup of UD 7.0
Make a new andvanced nandroid backup of DATA ONLY (uncheck all boxes except DATA)
back out to the main menu.
Wipe data/clear cache 3 times.
Install 8.0
Restore your backup of Data only.
That should fix your problem.
P.S. This is what i do EVERY upgrade for UD. It restores ALL of my settings, bookmarks, texts, apps, etc. So far it has never failed. I got rid of Titanium and Mybackup long ago.
