Dreamweaver MX 2004 Crashes on adding sites

My version of Dreamweaver (updater 7.0.1) kept on crashing when I added sites. I found deleteing the contents of the following cured the problem.

C:\Documents and Settings\{username}\Application Data\Macromedia\Dreamweaver MX 2004\Configuration\SiteCache

(these folders are normally hidden - you may have to use Explorer > Tools >
Folder Options to unhide them)
