I know this doesn't exactly apply to this particular category, but I can't seem to find a solution to this ANYWHERE!
If anyone knows how to fix this, it'd save me a lot of grief. I had the next strip for my webcomic about 80% done, I went to open it last night to finish it and suddenly, photoshop said "This file is not compatible with this version of photoshop" and wouldn't open. None of my other psds did this, just the one. I didn't open it on ANY other computer except my laptop and I haven't done anything to photoshop since I first installed it. If you have ANY idea how to fix this, I'd very much appriciate it if you would let me know.

Your psd file is corrupted, something went wrong when it saved last and it's probably missing information now.

I did a look around for some solutions but pretty much kept ending up at this place, might be worth a shot:

I've had that happen with word documents and never been able to get back my work. Good luck getting it back.

Thank you so much Skoolmunkee! That link REALLY helped! It wasn't a perfect save, but my line art was saved and that was the most important part. THANK YOU SO MUCH!

That link looks incredibly helpful. I'm downloading it, too. :D
