@msamavi stay away from them, they are a horrible company, I used their plugin for 2 years, and it was an absolute nightmare since day one.
At the end, after our site being broken over and over again with their terrible updates, we had to move on to a different solution and manually migrate all downloads (over 200) along with re-creating all customizations and theme modifications to adapt to the new product.
Their support is a joke, in my personal experience they will never solve anything for you.
I would not touch them ever again even if this product was absolutely free. If you value your nerves, stay away early. It’s the best that can happen to you.
