Maintenance for the week of May 25:
• [COMPLETE] ESO Store and Account System for maintenance – May 27, 6:00AM EDT (10:00 UTC) - 4:00PM EDT (20:00 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.
