I tried dragging the zip file to my wordpress plugins but I received this error: https://screencast.com/t/jVxdLi6DPO
Then I tried to unzip the file downloaded (WULogin.zip_bd146.zip) and I noticed for a split second I saw WULogin.unityasset but then it disappeared from my computer and I can't find it via Spotlight. Unzipping generates a giant list of folders: https://screencast.com/t/Fbbmb4m4y
Any ideas how to both upload the plugin to Wordpress and find the assetpackage to install on Unity? I tried submitting this question via your website but for some reason it wasn't taking the invoice number.
