I had a problem with my PS cs4 not opening files. So I uninstalled it and have tried to reinstall it but it would not. It claims my serial number is invalid.

When I contacted customer service they assured me serial number is valid. So what do I do.

By the way serial number is registered in my account with adobe.

NOTE - The CS2-CS3-CS4 activation servers have been removed from service

-So even if you have a disc or saved download, CS2-CS3-CS4 are completely dead
-Adobe also no longer supplies the special non-activation version of CS2-CS3-CS4

--See John Waller reply dated 1-1-22 There's a kink in the space-time continuum with CS4 activation.
Although the CS4 activation servers are officially dead, CS4 can still be activated for use on a fresh install on a computer where CS4 has never previously been installed. I successfully activated CS4 myself a couple of months ago just as a proof of concept
