Hi, it's been a few weeks since I last played, and I do not own Morrowind upgrade.
I tried to login and I get an error 201. I have checked that ESO (both 64 and 32), the Launcher and Steam are all exceptions in my Windows 10 Firewall. I also have them as exceptions in Windows Defender. I have tried running repair and I have verified I can login to my account online which is a different account/login from this forum. I've also tried running the launcher "as administrator".
So, do I need to buy Morrowind to keep playing the base game?
