So the other day I tried to open Photoshop, and it kept freezing when it was loading some part of it, and then eventually would give me an error that part of the preferences for the program had been deleted. It slowed down that day I restarted it. Now, when I turn it on, I cant even type in the first letter of my password without is going to the color wheel. The login screen disappears every 5 minutes as it keeps loading the screen over and over. It will not open in safe mode- the gray screen comes up, but there is never a progress indicator. I can't take it into apple without spend $50. Any fixes to try at home? I dont have any of the CDs, I purchased this from a friend.
