registering Cubase LE4 - License Server issue

Registering CubaseLE4, I entered the 32 digit activation code, and I get “license server not available, try again.” Ordinarily I’d think this is something from the Stenberg or licensor site end, but I’ve had such a difficult time getting to this point, I’m still not sure if I’m doing something wrong. Can anyone provide any insight on this?

Many thanks.
