Login issues

I am trying to log into the server from my laptop – The SAME laptop I’ve been using for months – And I keep getting the following message: “There was an error signing in” … But comes AFTER being told I have successfully signed in. And obviously I AM signed in on the laptop, because that’s where this posting is coming from, and I am also signed in to this account on my TV! Unfortunately, the only way I can edit the libraries is via the laptop so …Anybody have any suggestions?
