Chaps has anybody comes across this before: Playing a genuine copy of MW2, with disc in drive, not hacked and no cheats anyway or form. Shoot someone with a silence TAR-21 - last of 20 needed for unlock - some numbers (such as (1.224424012+0202020) or something) in brackets and in in-game font, appear on screen, and I get made a 2 star general. Next kill, which corresponds with 60 down the red dot sight, and bam - more numbers as above and I get made a 5 star, level 70 - I was barely a 1st Lt and enjoying working through the multiplayer challenges. Now, all weapons and challenges are unlocked, althought not cmplete - and the rank stuck when I left the game. Has anybody come across this before? DoIhave some sort of virus? Is this going to really p*ss off steam or some such and get me banned? Thanks for any help.
