Payment Plug in Authnet ED

Hi, Greg here in California USA. I am installing Event Booking Pro and need to install (or want to install ) the payment plugin Authorize.net ED.
I opened Membership Pro Component  / Payment Plugins // at bottom of the Payment plug in list page, I located my payment plug in file . ticked Install and got this message
"Could not find xml file in the package"  I also tried to load the unzipped download as well. The choices for Authorize.net are confusing  Sim, Aim, etc so I may not need this plugin however, please advise so I am ready for the plugin if needed. 
/ My Joomla is 5.4.6
/ Event booking is 5.6.1
my front end template is Cassiopeia  
Thanks in advance
Greg

Hi Greg

That's strange. Could you please submit a support ticket sending us super user account of your site? I will check and install the payment plugin for you

Tuan, Thanks for fixing this for me. Your service is truly fantastic. I see that I most likely unzipped the download into the same folder and must have forgot to open the unzip folder to find the file to load into my admin.

Yes Greg. The name of the field contains unzip_first , and we also have details instructions for installing the payment plugin at docs.joomdonation.com/eventsbooking/basi...ze-net-accept-hosted
