A Qualifying Product Does Not Exist

Question

So I bought a new computer and now I want to download my CS 6 products. I have the serial number but when I type it in, I'm told that there are no 'qualifying products' on my computer. Now I have to choose one from a list and provide that serial number.  I choose 'CS 5' because it's the only choice available. But Adobe has conveniently discarded all references to 'CS 5' from its downloads pages.  I can see CS 4 references and serial numbers, even CS 5.5, but those are not choices.  Fortunately I purchased CS 5 in a box--an option Adobe is moving away from.  I had the serial number even though thwarted by Adobe.  Recently in a survey Adobe asked why anyone wouldn't want to move completely to the cloud and stop buying products in boxes. Well, this is one reason why Adobe!! 
A similar incident happened with Adobe Acrobat.  I was happy with Acrobat 8. But they downloaded a trial for Xl and said my 8 would reappear when I deleted Acrobat Xl if I chose not to purchase.  I chose not to purchase and deleted the Acrobat Xl as instructed.  Surprise! My Acrobat 8 did NOT reappear and I had to go to the download area.  Surpise again when they told me they no longer supported Acrobat 8, and I wound up paying $139.00 for an upgrade. Do I think Adobe is doing this purposely? Yes indeed.
Adobe, you are getting too much like Microsoft with your Cloud ideas and renting space on your "cloud" servers.  Why don't you get smart and help people up instead of exploiting people as if we are tenants of Adobe?

Thank you all for your responses.  Once I removed the value from NEW_ITEM-MATNR[1] they were able to successfully receive the product into their system.
