I just purchased the professional upgrade from Artist for Studio One 4. I went to "Studio One Activation...," checked "activate my purchased version of Studio One," put in my product key, checked the box for "I have purchased an upgrade for Studio One," then pressed Activate. I signed in to my account, but then it says "An error occured at the server (Status 200)" while its "activating product."
I use Windows 10. I tried uninstalling and reinstalling Studio One, and restarting my computer. Thanks in advance.
