Not 100% sure why this happened, but it has happened to me before. Usually it doesnt last 7hrs... Just try restarting and logging back in (usually wait like 30mins first).
I got a notification of the latest SL viewer update.. So I tried updating and I got the following error. See link--> . https://gyazo.com/1c0d84ca4022eb44f12ef646bd440de1 I dont know what is going on. Any feedback would be appreciated. Thanks!
