Hello,
I experienced this issue on NMM with Skyrim a few weeks back. This time it is Oblivion NMM on my Laptop. I get the same message "Cannot reach the nexus server" even though I can and am in fact logged in... Basically it is rejected my password even though I have checked 100 times, changed capitals etc. and I know its right. Basically I solved it last time because I was able to update the nexus but this time ive hit a brick wall, because I cant find a way to update my nmm? Its so irritating! Any solutions?
