I'm sick of this now! Help ok Custom Battle problem

[A Very Super Market]

If your SP EB works fine, all you need to do is start up RTW from steam again.

Although you couldn't open MP EB, it's already changed the stuff around to the MP configuration. To get around "Can't find steam" simply start it from steam itself, and it should work.

If you want to return to SP, do the same thing. Try and open SP EB from the start menu. It won't work. Then you open it in steam.

Edit: I see you have a few threads on this subject. Can you play EB at all?
