This is response to:
"My game keeps freezing up. I have tried everything from playing on a different Xbox to deleting my game and starting a new one. I bought a new hard-drive in case that was the issue, I exchanged the game for a new copy, nothing has worked. Customer Support totally ignored my question and instead game some bs about not giving out extra golden keys, I never asked for a key, I asked why the game keeps locking up.
Can you give us a hand or at least an answer? We have been looking forward to playing this game. Thank you very much."
I've played a bit of the 360 version of the game and have yet to run into any freezing in the game; however despite this not being a widespread issue, I'd like to assist in this matter. From your message I can see that this happened with another console and another disc. This narrows down the possibilities a bit; however there still are several things that could be causing this freezing situation that is being experienced.
I'd like to check a few things. First let's try to clear your 360 HDD Cache:
Clearing the cache may be able to help us here. To clear the Xbox 360 cache go to Settings > System > Storage > highlight the HDD > press Y > select “Clear System Cache”. Select Yes when prompted to perform Hard Drive Maintenance.
* = Deleting the cache will remove temporary game files and updates. Saved games, profiles, DLC etc will NOT be removed.
Also are you using any sort of USB flash drives with your 360? Is the HDD that's connected an official HDD or is this possibly a 3rd party drive that's been formatted to FAT32 to accommodate the 360?
Is this machine hooked to the Internet? I've sometimes seen 360 profiles themselves cause issues at times. Can you please try, for testing purposes, using a new Xbox Live silver account to see if this is specifically on one 360 account?
If you have any other questions, or have any further information based on the questions in the above message, please reply to this email. Thank you.
