Ugh. My filters are gone.

I opened up Photoshop this morning to work on my website, and uh-oh! Most of my filters are gone (Artistic, Brush Strokes, Pixelate, etc.) I looked in the folder and they aren't there. I don't how they disappeared over night. It isn't a virus eating up my files because I've checked for one... It just blows my mind! (lol) If anyone could help me out on this I'd really appreciate it.

Hmmm.... maybe a hard disk error? Try using CHKDSK (or scandisk depending on your version) to see if there is something that can be fixed. Beyond that, you'll probably have to reinstall i'm afraid... :/

Yes, thats what I had to do; reinstall. It wasn't a hard disk error. I don't know what happened to my filters (lol) Hopefully they don't decide to disappear on me again. Thanks for trying to help, though.
