Problem:
Macromedia Dreamweaver MX2004 crashes when you try and open it. It doesn't even appear at all before the window 'report error' box comes up.
Solution that worked for me:
1. Navigate to:
C:\Documents and Settings\<<??>>\Application Data\Macromedia\Dreamweaver MX 2004\Configuration
(Replace <<??>> above with the name of your Window's profile. e.g. "Mark")
2. Delete the SiteCache folder
There is no harm in doing this as you're just removing its memory of what files you have in your website (presumably this memory was corrupted). Next time you load Dreamweaver it pops back up, and re-creates the cache file.
