I think I have stumbled upon one of the factors of our inability to download patch manifest updates from Zenimax.
I did a tracert launcher.bethesda.net in cmd window and watched as the trace ran into 5 different Amazon servers (identified using WhoIs) and then died at time out. I really wonder if Amazon has a misconfigured set of routers and are inadvertantly blocking access to bethesda servers?
Can the Zenimax/Bethesda techs look into this? Not being able to re-install the game after re-subscribing is very annoying.
