Adobe GoLive serial number won't activate [CS2 is dead, locked.]

I have many licenses of CC for my company.  But I have several old licenses of CS2 that we own.  I have a lot of content built in and administered in CS2 Adobe GoLive.  The computer we had it installed on has died.  I have re-installed it and went to use it and the serial number.. a valid, original serial right off the label on my original adobe box for CS2..

"THE SERIAL NUMBER YOU HAVE PROVIDED IS NOT VALID.  PLEASE CHECK YOUR SERIAL NUMBER AND RE_ENTER IT.

OK, after a dozen times with and without the dashes its a no-go.  So, I get another one of my valid adobe licenses for CS2, same thing.  None work, adobe has nailed me from using the damn software we purchased in single box licenses.  ITS OUR SOFTWARE.  WTH?  And before we get a play for dreamweaver, NO< I don't need to spend 6 months figuring out where all the tools are to edit a quick html.  I just want to use and update the content in GoLive easily and quickly with no learning curve at all.

Of course you can't call or contact Adobe except when the call to harass us with phone calls to try and sell us more CLOUDs.  Not Cool Adobe. 

Any ideas?
