Hi terrapin
I've got a problem too....
After registering at the download central, I use the link come with the verification email to activate my account, but nothing happened, it just show me the frontpage of the download central.
It still told me "Your account is not activate. If you have just registered your account please check your email inbox for the activation email." if I try to login.
Have tried with 2 email address, 2 ISP, 3 computer, 3 browser (Opera 9.2, IE 6.0, Firefox 1.5.0.4), no combination works.....
And as SteamWake said, the frontpage of
http://picturehost.realsimulation.com/ is some kind of strange.
