So I started up photoshop this morning and it gave me an error about loading actions. So once it started I noticed all my palettes were reset and my actions weren't loaded. I went to load them and all the actions I created are gone

I can't find them anywhere and didn't have them backed up in a different folder! So I guess this means I've lost them. Has this happened to anyone else before? Even after a restart the actions are no longer there, so is there somewhere else the could be stored on the computer? I haven't restarted the computer yet, only cs2.
