Licensing CVS Proxy

Hello,

we have a little Problem with our License of over CVS Proxy.

When we install the Version 1.2.x and make a check out for a license via
the URL www.pushok.com is everything fine !!!

But when we try to install the version 1.5.0.6 (the newest Version) then we
get an error (Attach 2).

Is this okay ???

And is it possible to get a license for both versions ???

What musst we do to get a license for the version 1.5 ? Full Buy of 10
licenses ?

Thanks for your help !!!
