Marvelous Designer Sign Up Problem

This might be an incredibly stupid question but I’ve been looking around everywhere and haven’t found an answer yet.

I’m trying to buy Marvelous Designer with a personal subscription license, but everytime I try to sign up it keeps asking me for an “ID” which I’m assuming is the thing that I’m trying to purchase…

I can’t buy a license without signing up and I can’t sign up without a license,
am I doing something wrong?

I’m also not able to find any contact info since the contact page also asks me to sign in.
Thanks

Perhaps just a nick name?
