UR-44 VST licensing Problem with Cubase 7.5

First, I bought cubase 4.0. education in box.(Steinberg did not give the activation code, I could not find anywhere in the box.) However, to be used without problems

And after bought 7.0 upgade version made by C.D.
And bought upgade version through by on-line.

Now using cubase 7.5 with UR44.
But, When I open ur-44 vst(REV-X etc.)provided in my cubase, I get a message that they are not licensed.
How do I license them? :frowning:

I cannot find e-mail address of support team in steinberg web site.
