The latest version of ME is 1.8.5 and located here.. However, it seems like some incompatibility with PE, so could you, pls, send me your mission file and MissionEditor.log file for investigation? Thx.
This is exactly the same as the version 1.8.5 that was released back in June, correct?
I've been using that with PE. I've had only one mission that locked up and probably 25 that have worked just fine.
