I recently bought Star Wars: The Best of PC game pack, which includes Battlefront I. I really like this game, and i had a crazy plan to make my own maps. I downloaded Zeroeditor, but it doesn't work. It doesn't even start. It says: Error: You must have Star Wars: Battlefront I installed to use the Zeroeditor. But I've already installed it. I tried to reinstall both stuff but it didn't work. Please help me!
