Maintenance for the week of January 12:
• PC/Mac: No maintenance – January 12
• ESO Store and Account System for maintenance – January 13, 9:00AM EST (14:00 UTC) - 12:00PM EST (17:00 UTC)
I had this problem on PC. I had to close the client and restart like 4 or 5 times. Once I got in, I didn't have the problem again. This happened first thing after the last incremental patch.
