You aren't the only one who get a game who do very crazy things sometimes. I don't think that it's the copy, it's maybe the patch, or I don't know... (my MoHH2's copy is from my original disk, and we need a patch to launch this game).
For the game : Sometimes the copy works 100%, sometimes it's a bullshit... you just need luck. When you stop video games, it's very boring, like me, I stopped 3 wekks, but I've nothing to do.. so I'm a little back on moHH2 sometimes.
For deleting account : Sorry but I can't, I can only ruin the score (death by death), like I did for Stone. I don't have a cheat for deleting.
But you, you can delete your account, when you login, when you have "choose your player", you see "TagxHeadshot" and you can see the option : "Press 1 to delete your player".
But man, you are in top 100 legally, you are a good player. You have to be proud of that ! Do you think that rambo03 is proud of it ? He is about 25th for nothing ! Deleting your account is an error... trust me. It's not because top 100 isn't important that when you are in, you have to delete your account because you think that you aren't in legit. If you wont play anymore, there is no problem if your account is still here... and for the story... do you think that it's good to think that "you never existed on this game" ?
I'm happy to see the top 100... when I see the names, I remember the good old times. ShotbyagirlS is now 100
, Ryhmeur 97 (maybe in a few time they will disappear from top 100
but it's normal), Kinder 83 (about),...
Don't do it
