Installed 10.6.3 and now Photoshop CS3 won't open
Today, I had been working on Photoshop all day and at some point the computer got slow and it told me it had a software update. I decided to save everything I was doing, quit Photoshop and install Mac OS 10.6.3 hoping it was the answer to all the glitches.
Instead, Photoshop won't open at all anymore. I have restarted, shut down, repaired permissions, reinstalled the program, updated everything and it still won't open. It's the only program affected from my design suite as far as I can tell, but it's also the one I use the most!
Any help would be greatly appreciated.
