well here is the thing. i got my first xbox in 2007. my mom put her credit on the xbox. i bought borderlands for $30.00. my account got hacked so my mom canceled her credit card by going to the bank and getting a new credit which took 2 weeks. here is where the problem begins. i took my xbox back and got the new box slim 4gb. it didnt have enough memory to hold borderlands so i bought 8gb usb. i wanted to download it on my first account and use it on my second account since i got banned on blackops on my first account so i created a new one. when i start borderlands on my second account it sais cant launch borderlands. please help me.
