Thanks for your reply! My problem is with the final step... there is no way to play Campaign P, I can only play Campaign A. I followed all the steps you mentioned, but I'm stuck. I don't see that it's creating any new files anywhere, or if it is, I don't know where. I can load my saved file into the level designer, but that's as far as it goes (at this point, it's only a few objects, I just wanted to see it running before going further).
