When I upgraded to CS@ from CS I lost all of my actions. Is there a way to get them loaded or get them back?

Yep!!! Head to your Adobe folder in "Program Files" in your C: drive. Go to the CS folder and to your "presets." Copy all the applicable .atn files under the "photoshop actions" folder to the "photoshop actions" folder in the CS2 folder. Then when you start CS2 up again, go to the actions pallette and load the actions! (this is assuming that you are working on a windows-based system).

Thanks for the info Nathan. I tried that, but it seems that CS2 changed the actions in the CS and PS 7 folders. So my Kuboda and self made actions are gone.

May those old actions aren't compatible with CS2?

Try going to your actions menu which is on the right hand side of the actions bar and go to "load actions" then just select where ever you had them saved before. That "should" work.

Let me know if you have any problems.
