The others have answered these questions.. so i won't beat the proverbial dead horse.
Macromedia software is teh A #1 best software for your site building needs.. I have been building sites as a hobby and sometimes contracting my services out in my free time. I can tell you that Dreamweaver, Fireworks, and Flash are all worth the price... They are easy to learn, constantly have updates with new textures and extensions, work very well, and have plenty of tutorials. I swear by Macromedia (the only thing of theirs that i do not like is ColdFusion - mostly b/c it is painstaking and rather complicated). Get yourself Dreamweaver MX - you won't regret the purchase - it is expensive but well worth it! Personally i find Front Page combersome - it adds it's own extensions and coding to the actual code - which can be painful for editing in other programs.. not to mention it requires certain files that it makes to be stored with the site (and those files constantly corrupt themselves). You will see a major difference in perfomance and flexibility in Macromedia. You can not only do more.. but do more that looks good and works well and with less problems. Trust me on this.. You can't go wrong with the upgrade.. it is kind of like switching from PC to Mac.. you upgraded there.. well Macromedia will be your upgrade here! If you need help learning it.. Message me i will give you help with anything you need.. Also you can use the developers site on Macromedia.com to find tutorials and all kinds of prewritten code and lots of other cool stuff.. or shoot me a private message or e-mail and i will hook you up (as the Macromedia site can be a pain to find things you want if you don't know precisely how to look for things - and i most likely already have links to the things you need or i have stored tutorials or i can just give you the step by step). Let me know if you need help - i am happy to lend a hand!

Oh i almost forgot.. Studio MX is a good buy.. I suggest getting the full package b/c as you grow more used to the higher end you will want to add streaming content.. and you will need flash.. Firworks - no questions, hands down, definite need - i really rely on it heavily. You will need this for creating content rich navbars and other nifty contents and images. Flash.. well - we all know flash and it rocks! Free hand i rarely ever use.. i prefer to use Fireworks for that stuff. I use Director a bit too. Well i have most of the Macromedia stuff (contribute - waste of space - forget that thing).
What precisely are your needs?? I will then be able to tell you in more detail specifically what i recommend you get.

I couldn't view the page either.. but i am not sure whether or not it is my machine.. I just upgraded to the Dev Preview of 10.3 and haven't had the chance to re-install all of my Macromedia softwares. Before the upgrade i had no problems with any pag in the Macromedia site -- I am not sure if i have been to that page though.. I have been all over the site though. Try installing Flash MX preview and see if then you can veiw that page.. perhaps it is the Flash Player that is causing the problem -- Flash MX has it's own player that it will install with the App. That might fix your problem.

The link gave me the same error. Before submitting a bug report I check to see if it works in IE. The link gave IE the same error (with cookies always accepted). So it's a problem with that page, not with Safari.

If you do a lot of web pages, seriously consider getting Macromedia Studio MX (do you qualify for education or government pricing?). You will probably want the other applications later and the package is a better deal. If you are doing very simple text pages, you can always save as HTML from Appleworks or Word.
