I am using TI9 with XP and SP2. After upgrading to build 3567 I did a full back up, which appeared to be successful, but when I tried to verify the file I got the message that it was not a True Image file. All previous files backed up using build 2337 were recognised as True Image files. I re-installed 2337 but had the same result until I physically removed TI9 completely and then installed 2337 from scratch. It now works perfectly again. Is this a recognised problem with build 3567 or is it something more sinister?
