My Photoshop quit working because it says the preferences file was deleted. I don't know how this happened or what it means. So I tried to reinstall my photoshop. I have the disk but not the case so I "chatted" with Customer Service and they sent me my serial number. It doesn't work. I went back to them and got the run around from Chat then was finally told to go to the forums. That did not get me an answer either. So I tried calling the customer service number and it is always busy. I'm very frustrated. I don't think I should have to buy a new version of photoshop because I can't get any help from Adobe. This is ridiculous.
