Install Auctionblox and Paypal on my OScommerce store

I actually already have it installed, but it is broken and needs to be reinstalled with the latest version being used. You will also need to swap out the Paypal module installed in my store for a newer one in order to auctionblox to work. Please only people who have worked with the PayPal module and the auctionblox module need apply. I need this fixed Yesterday, so it is urgent. I do have a testing environment so that you may test the code changes before moving the files to my live shop. thank you.
