Are the Rock Organ_Medium files missing in Music Creator 6 touch, downloaded from Steam?

Hi dears.
Would like your help to understand the step 4 of " ► Finding and previewing audio loops" tutorial 2.
It seems that is missing the Rock Organ_Medium files in my MC6Touch or I am looking in the wrong place .
 
Details of my issue follows below:
 
In the step 4 of  " ► Finding and previewing audio loopspage" tutorial 2  I am requested to select "Rock Organ" in the "Content Location" as stated below:
"In the Browser, click the Content Location drop-down list and select Rock Organ."
Note that in the print screen of Tutorial 2 those "Rock Organ" files are shown.

 
In fact I can not find any Rock Organ_Medium file in my installation. I have searched in whole hard drive and nothing was found.
So, please, am I looking in the wrong place or are those files missing? As shown below I can not find then in my browser.

 
That issue rises a secondary question: How should I proceed to ensure that all bundles (Modern Strings, Guitars, Steinway Grand Piano, Vintage Keyboards and World Instruments) were correctly delivered and installed? .
 
Don't know if it helps but I have bought the "Music Creator 6 + Sound Pack Bundle" using my Steam account.
As shown below that bundle has following Cakewalk Expansion Packs: Modern Strings, Guitars, Steinway Grand Piano, Vintage Keyboards and World Instruments.

 
Any help will be very welcomed.
Thanks

I do believe there is slightly different content between the 2 versions. 
 
As far as the packages, once you have downloaded them, follow the instructions for installation of each. All of the new sounds will be installed into the Cakewalk Sound Center synth. Open it and search for the particular sound and you will find it there.
 
I bought and installed the Steinway pianos and the world package.... the instruments will be under various categories and not grouped as "world" in a group... world stringed instruments will be under the strings category, percussion will show up under percussion, etc.....the pianos did all show up in the piano category of course.
