Photoshop :: CS3 Repeat Registration Under...

I just upgraded to CS3 on Windows XP and every few days I am prompted to register. I registered twice and then spoke with Customer Service who could not see the registration so they manually registered me. Since then the registration screen appeared again and I registered a third time.

I just spent 4 1/2 hours on the phone going back and forth between Adobe Customer Service and Photoshop support. Customer Support wants me to return CS3 and buy it again under a different customer number. Support wants me to uninstall all Adobe products, delete the registry branch under HKLMSOFTWAREAdobe, delete all Adobe content under "Program Files" and under "Documents and Settings", create a new user account, add that new user to the Administrators group, then reinstall all Adobe products using that new user account.

I asked support where Photoshop CS3 records the registration information and was told that since CS3 is a new product, they do not have that level of technical information.

Has anyone else had a registration problem with CS3 on XP?

where the registration information is stored? If it is stored in the registry, I should be able to manually enter the keys and data.
