If you log out of the launcher it doesn't appear to let you log back in either, without even trying to launching game.- so it's likely an auth server issue.
Some thing happened during the May 19th double XP weekend, SOE did you really fix it back then? or are you just bad with coding?
I was browsing the Camo's after a death and when I went to make a purchase the transaction wouldn't complete. I thought I had a bad connection so I rebooted and now I'm getting this error as well. I've re-validated assets,but still no go.
