I have to say, this is pretty crummy. I tried to upgrade my software, too. I
own studio 8, cs1, cs2 and now cs3 design premium, which doesn't include
contribute.

I spent over an hour with customer service only to be told the same thing. I
didn't see the info on the site, and there is no trial version available for
mac users.

I've put in a case on friday to reverse the charges and still haven't heard
back. Customer service is really lacking at Adobe. I left Quark for this very
reason. Their customer service was the worst and now Adobe seems to be going in
the same direction.
