After plugin use, had new wordpress set up, no website

Hello this plugin was suggested in woocomerce pages as a fix to having no download link supplied after making a payment through paypal. Once the payment has been taken there is no download link.

I installed and used the plugin as instructed. After plugin use, the page turned to a new wordpress install, and i had to start from a fresh.

I completely lost the website, no pages, no images all gone..

I had to re install from a previous back up of the database to recover the website.

Do you think there is a safe way to install this plugin and fix the small problem of not getting a download link after paying with paypal and getting the link to download the PDF?
this was suggested by woocommerce as a quick solution to this problem, but it did not work out such a quick solution.
