It is quite difficult to accomplish what you say.
I tried to contact the distributor at the official support e-mail firstname.lastname@example.org but the e-mail bounced back because their mailbox was full.
So I tried to contact asknet Customer Service and I asked them about the dongle and they replied with an activation code (see below).

Hello I have today purchased a copy of Steinberg WaveLab. This copy however requires an eLicrnser dongle. Will I receive a dongle by postal mail or I have to purhase one if the software was delivered electronically. Thank you. Tomas Zahradnicky
