I just installed Photoshop CS3 and now InDesign CS2 and Illustrator CS2 won't open. I tried several suggestions from the Adobe web site tech support but nothing works. I can open these programs, however, if I reboot in Safe Mode (holding down SHIFT key). One of the Adobe web site suggestions was to remove all the StartUp items and add them back one at a time to isolate the problem. I'm hesitant to do this in case I remove something that will lock up my computer. Any suggestions? Are all the StartUp items necessary?
