Okay, in my game the new vegas neon lights were gone, so I tried to uninstall all my mods to see if i could fix it. Now my game crashes the minute I load it up. I had been using Requim for the Capital Wasteland and had Mothership Zeta Crew installed, it wasn't activated just installed. So I got rid off all my other mods except MZC and the lights weren't back, so when I uninstalled MZC my game crashes on loadup. I reinstalled the mod and it still crashes. Any suggestions?

Could be because your character is in a location or holding an item which has mod changes to it.
Tried loading from previous saves prior to the mod?

Actually the minute I start the game (as in the nv launcher) and I had already started a new game.

It must have been some issue with NVSE or something because starting it via the default launcher worked.
Thanks!
