Well its offical i hate hackers who force stuff on people who are trying to earn stuff.  i fell victim to them on MW1 tryin to earn a silencer for the AK-74u i had 2 kills left for it,  then i joined a hardcore match and lost my ability to earn anything at all from a hacked match something about a teamtier hack thingy.  i would like to know with out re-prestiging about how to fix it i just reached lvl 51 in prestige rank 2.  all my challenges are ****ed i cant earn anything for my weapons the weapons i did earn every attachment for are the M4, M16, MP5, P90, M60, M249 and the M21 also i have the digital camo for those weapons too.  i wish hackers would leave games alone.
