Getting this error. Not sure what else to do - I checked my account page and everything seems normal..
You're not the only one with this issue many people i play with are having the same issue but refuse to report it because of their awful customer care quality issues at this point. Best i can say is report it and hope someone in staff cares enough to actually bring it up and fix it.
I would also check your username and or password is correct just iin case as sometimes programs you use to save that stuff mess things up.
