I had to uninstall Ref 4 Studio, a while back, as I was having problems with my system. I now want to re-install it, but can't find my activation key. I've looked everywhere I can think of. I contacted Sonarworks support, and attached a copy of my purchase invoice, to show this was a genuine request. That was over a week ago, and I am still waiting for a proper reply. Is this poor customer service, normal with Sonarworks?
