I used the trail version and really liked it so I bought the full version on iPad 4. As soon as I tried to sync my notebooks via iTunes I got the blue screen of death. I've tried disabling autosync, restoring iPad to factory settings, etc. but now I can't even download the Outline+ without the iPad showing me a blue screen. It is extremely inconvenient and sometimes I can't even turn the iPad on without getting the blue screen, and I have lost information and time.
