Hey guys, i could really use some help with one damn achievement.

Hello everyone,  I'm not really sure where to put this topic, I never was  good with forums. I do need some help though, I have had my xbox for a good time now, but i have yet to get all 1000 achievements in a game. Then i got skate 2 when it came out and I love the hell out of it. I got every achievement except for the damn freeskate challenge one. I even got all the DLC achievements and there is nothing worse then seeing you have 59 out of 60 or whatever. The problem is you need to finish all of them with your created skater, but when i first started i must have done one or two with an in game character. It says i completed all of them, but I still am missing the achievement. I need someone willing to go through a couple of these with me, i will return the favor anyway i can. Ill help with achievements for you on games i own, or I'll go rent the game, and if I can't find it, i would even consider buying it. I just want this freaking achievement man. Thanks guys- Kurt
