Trying to activate a Cubase 8 trial but dont receive activation code


I’m trying to activate Cubase 8 Elements trial, because I need a Cubase 32 bit version, in order to work on some old projects.
I’ve never owned a Cubase product, so this is rather new to me. Also I dont wanna buy it now, just do some work on some tracks.
My main hurdle is tho, that I dont get any activation codes, via mail. I tried 6 (!) different mail accounts by now. And yes, I checked the spam.

Not, sure, if I can actually launch it, if I get the code, however it is asking for it, if I start it. Someone told me, that its not possible to have trials of old versions. Can anyone confirm this?

Any suggestions? I guess, I might call the support.
