[Problem with mods]

I have used Nexus Mod Manager before but not on Fallout New Vagas. I have lately tried to download and install weapon mods and stashes for starters but when they are activated and I go into the game they do not work, they are not there. If anyone could help me sort out this conflict it would be great.

I really don't understand FOSE, I link or advice?
