Forum:Leveling xp bug HELP!!

so, after a week of playing the game. i took my xbox to a friend downloaded my mercenary pack and did the patch. i started a new game and now after 7 hours of playing the game for a 2nd run through. i am unable to level up. i'm level 1 still and i've been running around killing shit and I've done five quest so far. my xp i at 4024/200. i cleared my cache and this didn't fix the problem. i'm on the xbox 360, any help will be great thanks - Mrmuad
