you can't...there would have to be a patch that fixes the bug and you won't be seeing one soon. The cause of corrupt save files are glitched areas and quests like vault 3 and fly me over the moon. The best thing to do while playing is to make pre-saves before you start a quest chain. You will have to reload with a previous save and avoid the area/quest to avoid save corruption. If you did a glitched quest early game and saved on all files that you may have to start a new game (happened to me)
The Best thing to do is restart the game and play again. I had a glitch at the very start wouldnt let me lvl up so i started over worked fine ( might do it more than once)
There are no cheats in Fallout New Vegas yet. It's to new. Plus if you want to cheat you have to be using the PC and not the Xbox360. But there are some glitches and bugs that give you infinite EXP.
Occasionally Fallout: New Vegas will freeze, but not as frequently as Fallout 3.
fallout: new vegas 2 I've heard.
Fallout: New Vegas
Fallout New Vegas is the fifth installment in the Fallout series. It is for the Xbox 360, PS3, and the PC.

No, you can't get married in Fallout: New vegas, but you can have sex in the game :)
fallout new Vegas will be on PlayStation 3 and Xbox 360
In my opinion, Fallout 2.
There are no drivable vehicles in Fallout New Vegas, unless added by a mod.
Fallout New Vegas is all one game.
