I am having the same issue. I found another thread here: http://forums.nexusmods.com/index.php?/topic/713390-nexus-modmanager-links-to-mod-updates-broken/ The thread is from Jun, so this has happened before. Basic answer: "This is caused by temporary Nexus network issues, it will usually fix by itself within few minutes, requires a NMM restart." I am just going to continue playing and hope that the admin folks fix this for us. Cheers! Best of luck. And you English is fine.
