Purchased the wrong version of the plugin

Hi,

the plugin we purchased has 2 versions: Standalone + Wordpress plugin.

We purchased the Standalone by mistake when we should have purchased the Wordpress plugin.

I’ve contacted the author but i’m still waiting for answer, still i don’t know if this has to be solved by envato.
Nonetheless i would like to know what to do in this case? What we wish is to have access to Wordpress plugin and pay the difference.

Thank you for your time.

Please wait for the author reply. If both version plugin published in the same author portfolio then there can be an easy fix. lets see what is author response.
