I accidentally disabled the NMM to launch when trying to download stuff to the mod manager (The pop up at the top of the window asking if you want to launch the application), and now I can't download anything through the mod manager. Could someone tell me how to enable it to launch?

My Fallout New Vegas has not successfully launched in a long time. When I take off all my mods, and after uninstalling and reinstalling, and launch it it works fine. Oddly enough every time I add a new mod while in a playthrough it just screws the game. I do not know if it is because it is being weird or conflicting with mods, but it makes it to where i cannot launch the game without it crashing at the "Bethesda" screen. Is there a program that I can use to check mod compatibility? I haven't been able to find information on it. Plus i haven't been able to launch the game in at least a month. If anyone one could help in any way it would be much appreciated.

I have just gotten fallout new vegas and downloaded some mods but dont know where to find them to add them to the game. If anyone can help me it would be much appreciated
