i would try to play the same disc on another friends account if possible.

play the same disc on your account on a different xbox

try playing on someone elses game online with your account
*(or rent another game)

hey if you rent the game maybe you can just switch the discs lol

if not call up rockstar games and ask for a refund or replacement

do you need a "rockstar games social club" membership or account to play on xbox? i know i do for pc.

oh and to the last guy:

xbox is fking awesome so stfu
it cost like 150 new
it has a mass amount of games
its easy to mod!!!!
connects to your computer to stream media easily
mine sorts trhoguh over 150 movies that are saved on my computer hdd and the xbox lists them quickly and plays without a problem.

yeah ps3 is cool but blu ray is not a good selling point for me, price is still a con, even though its 299 now its still more than the xbox.

xbox has a larger online community

but if i had to say a final word i would say

PC!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
