I am also having a problem getting ME to run with WOFF PE. Everything is fine until I try to load the mission file for editing. I get the window that says "Loading mission file..." but that's as far as it gets. It will not go any farther. I have downloaded the latest ME from Sandbagger's Mod page and reinstalled it and have tried it with different pilots and different missions but the result is always the same - it hangs on the "Loading mission file..." screen. I am running vanilla WOFF PE, no mods of any kind.
Any help and direction on this will be much appreciated as I dearly love using ME. Thanks!
