UI errors in multiplayer after using MXT client for multiplayer services

Hey all, I've just recently used MXT to add cryptokeys and max levels to my account. I deleted the menu and process hacker and now whenever I go into a multiplayer match after i pick my class I cant use the menu. When I press esc it says UI Error 27393. Anyone have a fix?

Your issue is the way you did your stats, I used to see this when someone went straight to prestige master level 1000 from level 1 without going to 10 level 55 first, the game couldn't process their stats correctly. I can fix it for you since you're on PC, or reset your account, then go to prestige 10 level 55, play one game so that your rank goes to prestige master level 56, THEN go to 1000. Also be careful with Keys, as too many will give you an error in black market.
