Purchase Code

Dear Sir,

Via Envato CodeCanyon, I purchased the full version of the Multi Currency WP-WooCommerce plugin.
But I can’t install the downloaded zip-file.
When uploading the zip-file in the WP-Plugin manager, I get the feedback, that the zip file was extracted, but does not contain a plugin and therefore can’t be installed.
I thought it might be caused by the fact, that I had not installed the free version first and so installed that one. This installation went fine, but still I can’t install the full version from the zip-file from Envato.
I have downloaded the zip-package from Envato repeatedly by now, but had no success with the installation, though I followed the description in the documentation.
I have WP Multiuser installation with WooCommerce, all running with the newest updated versions). The plugin was intended for one subdomain-site of the installation, so I thought it would not interfere with the one Regular License purchased.
I have also checked my Server to have the recommended settings for the plugin.
Is there a known issue with the Envato zip-package or is my MultiUser installation the cause for the problems?
How can I install or activate the full version?
Thank you very much for your help!
With kind regards,
