I'll try to explain it best I possibly can. I just bought the Adobe CC All Apps package for teachers about three days ago and the past 72 hours I've been trying to fix it non stop. I can't find anyone else having this issue but basically what happens is I'll open a CC app and it opens up and works perfectly normal for about 1-5 minutes then all of a sudden closes with a message on screen saying "Save changes to 'untitled'? YES NO." Any option i click causes the program to exit. Keep in mind this also happens in every single app! I've tested them all and this weird bug appears. I've already tried uninstalling/reinstalling, updating graphics card drivers, disabling firewall, deleting preferences, contacting support multiple times (I gave them remote access and they used CC Cleaner and other apps and claimed, "The problem is now fixed" however it still doesn't work.) I've done just about everything except reset my whole PC. I have used adobe CC products on this computer before in the past.
