Well, this is weird - It's back on line, nobody seems to know what's going on, but I'm just installing Acrobat 8 for mac and it seems to be OK - I'm a legit user of the PC version so I won't feel guilty about this if it turns out to be another error. See
http://www.adobe.com/downloads/cs2_downloads/index.html The general theory is that Adobe have decided that it's so old that they might as well give it away, but there has been no official announcement. It's safe to assume that there will be no support for this whatever!
