Ok this is bad,im playing the game,and it closes,and it says error game has to close,sorry blah blah blah,this is the 6th time.Its ruining the game.What can i do.please.

Which MM game specifically? (As we don't have subforums for all the MM titles :) )
Does this error occur on any specific game event, or is it random?.

Ok,im really getting mad,MM6 just keeps crashing,all over the place,never in the same place.I want to finish this game.But its totally imposible when it just crashes constantly,please tell me how to fix this.thankyou
