Did you use this link?

I’m not sure what would be wrong with the AAAmap v96 beta. But when you download it, there should be and .exe file to just double click on.
Now for the Motcreations map make sure you go here to download it:

And then you could get the A&A module for it from the aamc link.
Hope this helps.
