Question

Answer 1

In this situation you'll need to submit a technical support ticket by going to my.presonus.com - log into your user account if you aren't automatically logged in, select support at the top of the page and click the tech support ticket button.

Put the information in there, include your software key.  The techs can figure out what is jamming up the works.
