Now it's telling me it's assinged to another consol. I have only used this 1 Xbox. It's just a new hard drive.
I've seen this happen since I own two Xboxes. If you still have your Old HDD put it back in, log in with your XBL account, take a USB stick and copy the files to the USB stick. Then put your new HDD in, log in with your XBL account and transfer the files to your new HDD and you will be good to go. You can also transfer the rights to the DLC to your new console but I can't remember how to do that since I've only upgraded my HDD once in my 360 Slims.
