There is somethin on the web about login problems..

Hello to all our players!! We hope you are all enjoying yourselves in the world of Hero Online!

Several of our players have been letting us know of their problems logging into Hero Online. After some investigation, we have pinpointed many of the issues being related to user's having Hero Online blocked on their firewall application.

Before trying anything else (such as uninstall/re-install or contacting customer support), we ask our users to verify that Hero Online is unblocked on their firewall access.

Thank you
