The published modules on this site are what I download to my MLS. They should also work with your MLS but if they do not let me know and I can try to help find the problem.
The Raw Files are the Captivate file which can be opened in Captivate so you can make changes. After you make your desired changes you can publish them and post them on you MLS. You can get a trial version of Captivate for a month and try it out. We get our access through an educational discount through our university.
We have used the Lynda.com tutorials for Captivate and they decrease the learning curve on Captivate.
