So in the past i tried new vegas and because i liked it, i went ahead and bought it when it went on steam sale. To my pleasant surprise, it found my old save no problem. However when i launch the game from 4gb's exe, it does not detect any of the mods. This may be due to different drive letters but i am not sure. THe 4gb did not work before . When i launch from NMM, i get to the screen where i can launch a new game, continue, etc but then it CTDs. Any ideas? Would it just be easier to copy all of my content to the steam version?
