First. sorry for my EngLish :(
When i use move (M). the game crashed on the Desktop, or when changing character, server...but it doesn't happen often.
like this video :(
i am using Loui's MuEmu Server. if someone really knows the fix or the cause. pls let me know. thank you !

double check all client files maybe some files  is missing that's why it disconnects you automatically or check your maininfo maybe you made some mistakes

but sir. check where in client? Object and World or anything? :(
