When I go into Event Viewer and look at the Fallout New Vegas crash log (Application Error), I see Event ID 1000 with '0x80000000000000' in the 'Keywords' Field.

Again, I looked at the installed update history, and nothing in that field coincides with the game not working. It still had the same problem, even though I can't find anything with my computer that would have changed. So I restored the Fallout New Vegas folder from a backup that was made back when the game worked. My anti-virus program has not 'flagged' anything that Fallout (or any other app, for that matter) was doing, either before or after the failure.Īfter finding no driver updates and no mod conflicts, I figured it had to be something with the game, had somehow become corrupt. I didn't actively change anything between the time it worked and the time it didn't work, which is why I looked to see if any auto-updates (to Windows or any drivers, that is) had been applied. However, I still tried running the game without these mods just to rule it out, but no dice. It worked fine for a few days (and a machine reboot or two in between) with those mods running. I do have two mods installed via Nexus Mod Manager: Fallout New Vegas Anti Crash, and the one that adds more fast travel points, most notably the Vegas Strip area.

I looked to see if any driver updates had auto-installed overnight, but there was nothing. It's not just one save file, I tried several different ones and none of them are playable.

It worked one day, and the next day, it didn't work. I'm totally stumped as to why my game suddenly is unable to load any saved file.

All or nothing fallout new vegas
