I have the answer for the Addictive drums midi files...Yay!
They did change it on the website, but you can still get the downloads.
 
If you want to use the midi files with other drum software you need to do the following:

1. Log-in to your user account at www.xlnaudio.com
2. Go to this page:
http://www.xlnaudio.com/myaccount-myproducts/offline
(note the "offline" part of the URL, making it different than the regular My Products page)
3. Scroll to the bottom of the page where it says External Midi Files
