Ok, I find the activation code and put it in. But the upgrade License button is grayed out. There is a red zero with a line through it on my USB licenses and soft licenser as well. It is no license to upgrade selectable. No license to upgrade found. Please connect a USB ELcenser which contains an appropriate license to upgrade to your computer.
However when I try to open Cubase 7.5 it says I have to activate it. I have a session this afternoon, and there is no tel. number to call for tech support in the USA.I emailed them but I have a feeling I won’t get a response in time.
