Can't register on server

I just purchased pdfcreator plus, yet I couldn’t have it installed.
When prompted for license key, it read “No answer from license server!” I am using Windows 10.

Please refund.

Hello,

there were some issues with our license server which are solved by now. Please try again to activate PDFCreator.

If it is still not working you can if course get a refund. For a refund please contact us with your license key or order ID at support(at)pdfforge(dot)org.
