? about PS actions

I FINALLY got my photoshop cs4 installed (my computer wasn't playing nice with updates and such so I couldn't install until I got that fixed).

So now I have tons of actions from my PSE but they won't work in PS will they?

Is there a shadow action around? I was using one by Kim that I loved but not sure about if it works in PS?

You can try them. One thing I LOVE about cs4 is being able to drag and drop actions!!! LOVE THAT!!!!
