Got a bit of an issue where i dont have an internet connection for xbox360 at home but do for a pc (work) - is it possible to download this patch on my pc and then somehow get it across to the xbox??

Have lost about 15hrs of game play with a save-game giving me the DLC error and its driving me mental!!!

Somewhere on the Xbox 360 main website, there is a patch "package" you can download onto a flash drive. This will download every single patch ever released for any and all Xbox 360 games, which when put on a flash drive, can be transferred to your Xbox 360 and installed. If I find it, I'll post a link.

That should be the right one.

I didn't know that existed. Thank you for posting it!
