When you try to activate the theme with my key, the following error appears:
“API request call error. Contact your server vendors and ask to update the OpenSSL system library to version 1.0+.”.
I tried to reinstall the template and deactivate the other plug-ins, but I still get the same error.
Could you please disable all plugins that are not related to our theme and provide us your admin access so we can check it? Send us your purchase code also.

Please, check this problem with your hosting provider. It would be better if they will check this particular problem from their side because the error comes from PHP core.
