I purchased the Fireworks CS4 upgrade (for Mac OS X), based on information on the Adobe site that owning Fireworks 8 qualifies for the upgrade package.
Upon installing Fireworks CS4, my serial number from Fireworks 8 was NOT accepted. From poking around it seems that Adobe claims that if you own Fireworks 8 as part of a suite (which I paid almost $1000 for in 2006), you are not qualified. This is total misrepresentation since it was not stated on the upgrade path site.
I have tried calling Customer Support, but after being on hold with horrible music for over one hour, I gave up.
I want an explanation from Adobe on this issue... if no upgrade here then they have lost another customer.
