Sorry if this got posted before, but I couldn't find any relevant solutions to my problem: Every time I tried to log in to Nexus Mod Manager, it says "Login Error: Cannot reach the Nexus login server. Either your firewall is blocking NMM or the login server is down. Here's what I did after seeing the message: 1) Checked that NMM has an exception in the firewall. It does, and the firewall allows it through. 2) Updated to make sure I had latest version. I did. 3) Uninstalled completely, and reinstalled version 0.55.8. Still nothing. I'm not sure if the servers are actually down, since my friend says he can use his one on his computer, but I can't even login to the server from mine. Nevermind, I managed to get an answer from someone, I know it's been a problem for a while. edited again: Unfortunately, there is no way to fix it, the servers are down I've been told. However you can install them by another way - instead of downloading by pressing Download(NMM), press Download (manually) and download the zip file. Then, open up NMM and on the left there is an icon that look like a puzzle with a plus sign. Press that and it will take you to a file selection page. Select the zip file of the mod you downloaded manually, and it should be working.
