Data capture before Download

Hi,

I want to set up a section on one of my sites for visitors to download pdf reports.

In order to download the files I will want visitors to register/login via a data capture form to record, name, email company etc, and was thinking of using contact form 7 or similar.

There would be several files for download on the page, once logged in visitors can download as many files as they wish.

My question is this, how do I get the contact form and download manager plugin to talk to each other, or is there an all in one plugin solution?

I have tried using Contact form 7 in conjunction with Download monitor and Email before download, this seems to work for single files on the page, but not when i have several files.
