So I bought Fallout New Vegas just the other day because I am very interested in trying out the various mods on the Nexus. I made a Nexus account and downloaded the manager right away. However, once I found a mod I wanted to download, I found that I was not able to download the mod through NMM or even manually. When I attempt to download through NMM, a pop up window from the Nexus appears asking if I want to allow the page to open up the NMM application. After I allow it, nothing at all happens, whether I have NMM open or not. After becoming frustrated with downloading through NMM, I attempted to download some mods manually. The mods begin downloading in my browser, but as soon as they finish, every one of them say that they can not be read. I have searched for solutions everywhere, but nothing seems to work. Any ideas on what I can try in order to fix the problem?
