Why can't Absolut 3 be upgraded to Absolut 4 during the Grace Period?

I contacted Steinberg’s sales agent and they couldn’t tell me what the situation was. Let me send an e-mail to German distributors for inquiries. But I can’t find any German e-mail address.

I’ve been waiting for Absolut4, and I haven’t even installed Absolut3. I’m afraid I’ll have to uninstall it to install Absolut4. I hate to waste time on all kinds of computer installations.
