I made sure I had the latest version of FOMM, NVSE, and New Vegas. I decided to try out Project Nevada today, and it worked when I first installed it, but then I exited the game and re-opened it and I get the error 'There seems to be a problem with your Project nevada installation because the HUD extensions were not detected.' Everything I found for it didn't work. I'm sorry if this has been answered before, but I've been looking everywhere for the answer for about five hours now.
