Listen to DEMOS ??

[mrlewp]

Just viewed 4 posts after searching. One was over a year old, the others not very helpful. Totally new at trying Pro-Tools M-Powered (after about 10 hrs. just trying to get it to run on Win 7......... )
..... Now, I'd sure like to hear some of those "Demo" tracks taking up over 3G in the program folder- subfolder named "Pro-Tools Essential Demos". Sounds great, except cant find how to listen to them. I've printed a bunch of pages from the "User" and "Reference" pdf files. Sorry.... but I find absolutely no instructions as to how to call up any of these "demos" for listening.
FYI ; using the version that came with M-Audio's KeyStudio 49, and the "micro" adapter / interface. (yes, I finally figured out I have to take the sound from the headphone out of the adapter. Knew the jack was there all along, but didnt see a "must use" note on that. At first I left my speakers plugged into my laptop headphone out, getting no sound of course.)
So, where is this hidden functionality, ... and why? is it so secretive?
