Photoshop :: CS4 Extended Upgrade

I am using Photoshop CS3 (registered and activated) on my old computer. I built a new computer and want to install CS4 extended on it. I purchased a Photoshop CS4 Extended update from Amazon for $342.99. During installation of CS4 on my new computer I entered the serial number. The next page that pops up is Upgrade Check that asks: 1) Select product that you already own: The only choice is Adobe Photoshop CS3 Extended and 2) it asks for the serial number. I am upgrading from Photoshop CS3, not the extended version, so it will not accept my serial number. Photoshop is installed on a trial basis right now. I tried installing Photoshop CS3 on the new computer but that did not help and CS3 did not recognize the CS2 installation disk that I put in the CD drive to prove that I was allowed to install a CS3 uprade. The new computer I am trying to install on is an Intel i7 920 processor on a Gigabyte GA-EX58-UD4P motherboard, with 12Gb RAMM, a Sapphire Toxic Radion HD 4870 graphics card, and running Windows XP pro 64 bit. I installed the operating system on the D drive. This computer is not setup to connect to the internet. I am also trying to install Adobe CS2 Creative Suite (everything except Photoshop), but the CS2 installation does not recognize the Adobe CS1 disk 1 when I put it in the CD drive as requested. This is all very frustrating considering how happy I have been with my Adobe software all the way back to Photoshp 5. I called the 800-833-6687 number and after playing phone tree for a while was informed that I was calling outside their hours (at noon on Sunday) even though the webpage I got the number from says they are available 7 days a week. It was bad enough that after spending $195 to upgrade to Photoshop CS3, 3 weeks later Adobe announced Photoshop CS4.
