This is Starcraft Classic map I was working on. I solved the problem with the 0x004344A3 error by myself. It's a 1 human vs 7 computer player map. The used AI is Expansion Campaign Insane. You start at the top of a high but slim map and the computer AIs start at the bottom. To win, you have to kill the Overmind. You have a warp gate where you can upgrade normal units to hero units with better stats. (Maxed at 12 per category). Also you have a repair temple where you can repair some units. I changed the unit's stats a bit: Mostly, I added some shield capacity and then removed the hit points stats by the same amount.
