Topaz Gigapixel AI "Log in" "Permission Denied"

Anytime I try to log in to activate Gigapixel it gives me an error that says “Permission Denied” I’ve tried this on the latest version of 5.7.3 no luck, went to previous versions, still didn’t work. I own Sharpen ai, and DeNoise. They both allowed me to login, but Gigapixel won’t. Has anyone encountered this problem?
