Every time I launch MCC it loads for about 10 seconds and then I get hit with an error. The error says Easy Anti-Cheat at the top and the message reads; Unknown file version (C:\Program Files (86x)\Steam\steamapps\common\Halo The Master Chief Collection\halo3
halo3.dll). This error started happening after one of the updates and I could never figure out how to fix it. I can’t really find anything online about it either.
