I purchased the UserPro plugin and loaded on to my site. After which it states the following;
**You are using a trial version of UserPro plugin. If you have purchased the plugin, please enter your purchase code to enable the full version. You can enter your [purchase code here]
You have entered an invalid purchase code or the Envato API could be down at the moment.
I only have one purchase code and it doesn’t work. Return my money or the correct software/purchase code!
