Did the issue with PS just start happening? Have you made any changes to the system, such as new drivers and/or OS updates? If so, you could try a system restore, assuming you're on a PC (I don't know what the equivalent is on a MAC).

Note that a sytem restore will not affect a corrupted file. If the file is coorupted, you'll be out of luck, I think.

Also, If you need reinstall PS, deactivate it first, if you can, so that you don't lose an activation credit. You may be able find some help from the Adobe forums, or Adobe support.
