Every time i try to save my game It freezes up on me and i have to restart. I've look around on forums and i can't find a fix anywhere online. I'm playing on the 360 and if anyone can help me it's very appreciated. Thanks!

Hey man,
I had the same issue. I fixed this by removing all patches, (Note: do not Re-download them) fast travilling far away from the area you spawn in and saving. After that you can download all the patches and save normally.

sounds simple enough. But i looked under the FNV section in my memory/games section of my hard drive on my xbox but I don't see anything about an update. is there anyway i can delete a single update on my xbox?

Warrior,
Unfortunately their is no way to delete a single update/patch. The only way to delete them is to clear you system cache. If you don't know how to do that, search for a tutorial on YouTube.
