recently i was having trouble with my Fallout: New Vegas game so i had to uninstall the game from my hard drive (meaning that it already was installed) now when i try to install the game back onto the console the game won't even start and just give me a disc read error. but when the game isn't installed on the hard drive it plays fine, well as fine as the game will play with all the damn glitches it has. i just want to be able to install the game again and play from the hard drive cause when playing with it not installed it lags and takes forever at loading screens. i've deleted the system cache and the actual Fallout update (update no. 5 i believe it is) i'm just lost on what to do to fix this annoying error, please if anyone has any kind of advice let me know.
