FBP | Fast Bundle Product

The app just causes way too many problems on my site. Its' a great concept and worked for the time being.
EDIT:
I downloaded this app again, because the other app was a little too much. I don't know what happened, but it has been a nightmare installing this. The first time I installed this a year ago it ran smoothly during the initial set up. Now I tried to install it again, thinking it would be fairly the same and easy. NO... thier pages are missing, links are not opening up what they should and their FAQ is no help.
