Upgrade to bundle after Dropfiles lapse?

I previously purchased Dropfiles so I already have an account. However, I let it lapse and did not renew the subscription since I wasn't using it, but another extension instead. I have since reconsidered and would like to now purchase the bundle including Dropfiles/Droptables etc ($59), and I would like to take advantage of the sale price. I have an old, unupdated version of Dropfiles in my Joomla site now. How do I go about installing the whole bundle after purchase, including the updated version of Dropfiles? Thanks!
