That is a really odd issue you're having, but I've seen similar issues from ENB before - never found a way to fix it. However, I do know that it's been said on a few different forums (and in the Viva New Vegas guide) that ENB in general is incomplete for New Vegas, having not had some of it's features implemented - it was recommended on VNV to use a reshade instead.
That said, you might have gotten more and/or better help if you'd posted this in the Fallout subforum rather than the Grand Theft Auto one. It's an easy whoopsie to make if you aren't used to forums/bulletin boards, so try not to stress too much (and TBC, I'm new too, not any kind of authority - I'm just trying to be helpful).
