Need some help with Photoshop

Well, as the topic says, my shortcuts aren't working in Photoshop >_<. Like when I do a Filter > Render > Difference Clouds, and then want to repeat it, normally I could press Ctrl F. But I can't do Ctrl F, I have to re-do Filter > Render > Difference Clouds. Not even the command to merge my layers down (Ctrl E) wont work, neither does Hue/Saturation. Pretty much none of them work. Do you guys think I should just re-install Photoshop or is there a patch or something that could help? I'm using Adobe Photoshop CS.

reinstall

ah damn, I was hoping there would be an alternative to re-installing but I guess not. Thanks for the response Jing, I'll get to it later today.

Well CS2 is out.. Why not get that one when you are on the move..

Well actually, I got my CS working awhile ago (sometime during the forum downtime) and I did get CS2 to. Thanks for the help anyway TwisT! [img]i/expressions/face-icon-small-smile.gif[/img]

if this happens again the file is Default Keyboard Shortcuts.kys in the Required directory, anyone with photoshop could send it to ya
