All the funcom account pages have a 24 hour lockout for your IP address if you log in or attempt to log in more than a handful of times. If you’re using a correct password and it’s not accepted, try waiting 24 hours, or use a VPN or e.g. the mobile internet on your phone. Once you’re in, Hunni’s link should let you reactivate your froob accounts, and then you should no longer get the error message in game.

Hope it helps!
