I didn't make it!
hey , i wish to make my own maps on company of heros. BUT it wont allow me, i click on WorldBuilder.exe. and nuthin happenes besides a flash like it was coming up..... WAT DO I DO!!!!
If the map editor flashes and then turns off, and you have patch 1.7 or higher: Add (create) the file "datapreview" to your "THQ \ Company of Heroes" folder. (same location as the worldbuilder.exe) I don't know exactly why it needs to be there but it got my map builder working again.
