Pro Q 4 keep asking for license key
I’m having trouble activated my upgrade I restarted the daw , copy & pasted the license and still have no luck. Whenever I paste the license it tells me to restart my daw and whenever I do that the same thing happens over and over.

I see you purchased an upgrade license from one of our resellers. For an upgrade license to work, you also need a valid license for its base product. So if you have an upgrade license for Pro-Q 3 you would need a license for Pro-Q 2 or Pro-Q 1. Without a license for its base products the upgrade license will not work.
Since you have purchased the license through a reseller, unfortunately I cannot help you with that. I suggest getting in touch with your reseller to see if they can swap out the upgrade license for a full license.
