Photoshop :: Why Doesn't Customer Support Understand?

I recently needed to reinstall windows xp.  I have saved everything I needed to reinstall all my software.  My photoshop CS2 is the only problem I've had.  Since it was an upgrade my installation pkge is looking for a previous version.  I have the serial number, original reciept, confirmation number, case number and all other materials needed including a challeng code given to me 2 years ago when I upgraded.  After 3 hours and being kicked from Customer Service to Tech support over and over with a hold time of 15 minutes in between each one I was finally fed up.  Each person tried the same thing.  Ctrl/Shift/Dbl Click which does not work.  They agree my serial number is correct, they can see my purchase from the order number on my original reciept, but not one could give me a straight answer. They all kept asking the same questions over and over but none made sense.  Honestly I don't think there was a language issue either.  The last one actually said I should upgrade to CS4..... how could I upgrade that if I can't even upgrade to CS2 on my computer.  I have totally lost respect for the Adobe system of support.  I have 3 Adobe programs and I am waiting for the day I need support on those.  If anyone has any suggestions for me I'd love to hear them.  They would not give me any help other than to say I must have a previous version loaded before I can load an upgrade.....NO kidding!  But even though I paid and they see I paid for an upgrade in the past....they cannot come to the conclusion that the previous version would no longer be loaded on my computer.....I've upgraded...the previous one is gone.  My only hope is to get ahold of a previous cracked version so I can run my paid program through with the previous installed..... that risks my computer getting malicious files on it...which is why I did the clean install in the first place......
