One person (Angelicblu) indicated that they tried unsuccessfully to register with IE and Mozilla, then installed and tried Google Chrome and was able to register successfully.
Seems odd but it's worth a try. Even still, if it works, it works.
Thanks to Angelicblu for giving us this heads up. : )
SwiftStryka said Firefox works now. o.o (But Berserk_Fury says Chrome seems to be not working now. =.= )
