Activate UserPro

I get this error: Please note: cURL must be enabled to successfully activate your license.
But I checked it and my cURL is activated.

Hi

Please check again cURL has installed and uptodate version in your hosting server.
Otherwise please contact your purchased item Author.

How to contact an author to get support or for any technical query:

Thanks

Thanks of the reply.

Additionally, I also get this error message: You have entered an invalid purchase code or the Envato API could be down at the moment.

Could this mean that there is another problem?

Regards,
Lukas

please check back it again and make sure you didn’t entered any space at the start and end of the purchase code. if still issues then the best will be contact author, they will assist you. Thanks
