Registering S/N of Nero 9 Reloaded Problem?

I have Nero 9 Reloaded. Registered it on an older computer in 2010. Just upgraded to 64 bit Windows 7 Pro. Installed it and when I went to register it, it "had a problem" and asked if I wanted to register later.
Have a legitimate copy & S/N so can anyone help me hear? In trying to contact Nero with the problem, all I get is an address, no email.

Please help and thanks in advance,
