All four Corel product keys they sold me were verified by Corel as pirated. The software authorized OK, but Corel wouldn't recognize it as a legitimate installation. When I tried Kinguin's link to report the bad keys it repeatedly told me the service was unavailable and to try again later. An invalid key had to be reported within 48 hours of downloading and I was unable to do so. I contacted via an email link including my Corel correspondence. For over a week Kinguin kept giving me a runaround asking for information I'd already provided. I would strongly recommend avoiding this company.
