Problem: Photoshop Won't Open

Hey all.  I have a bit of a problem and was hoping someone could help me out.  My Photoshop program won't open anymore (I have PS CS).  I was using it earlier, making icons, and my computer froze.  I shut it down and when I went to get back into PS, it loaded everything (brushes, fonts, etc.) at the beginning but won't get past that first part and it keeps saying the program isn't responding.  ImageReady still works fine, it's just the actual PhotoShop that's giving me problems.  Do I have to uninstall and reinstall the program or is there any other way that I can fix this?

Any help would be fabulous!
Thanks in advance (and please let me know if something doesn't make sense) :D
