I'm connected to the internet by fibre optic cable, if that's what you meant. Packet Loss - 1.0%. Ping Sim 200 to 300 ms.
And yes, I've restarted my computer, but to no avail. And how long since I last used the viewers, well I'd say Firestorm about a year ago perhaps. Any idea what the issue could be?
