No, sorry. Forgot to update. It was a weird error code and the announcements section on the login screen was laso saying 'Could not connect to the server' or something of the sort.
I just had several crashes to desktop on trying to login to PC/EU server. I can't connect at all.
Never mind! It's not ESO, it's Windows . I had a major Windows update pending, and had chosen not to download and install it yet. However, it seems Microsoft has ways of not-so-subtly reminding me to do it.
After the various ESO startup crashes, 1 of my 2 monitors stopped working, and the other defaulted to a very low resolution. I downloaded and installed the major update, rebooted, and the monitors were back to normal. I then restarted ESO and it now works fine also.
