After using FireWorks CS3 for a few weeks on my pc (Vista Business) it suddenly stopped working, giving the folloing message: “The application Fireworks has unexpectedly quit”  and asked me if i wanted it to generate a crash report that is sent to Adobe.

After searching for a while, i found a solution in a post by user “nedsbeds” on Adobe Forums

You must delete the following registry key:

“HKEY_CURRENT_USER\Software\Adobe\Common\9\Sites”

Of course, after doing that, you will lose your site setting in Adobe Dreamweaver.
