I am having a problem with Dreamwesver (version CS3)

I had to re-install my PC and have setup everything again from scratch. However now when I try and open any dreamweaver pages on which there is dynamic content Dreamwever crashes. The page does open, it's actually when I try to make changes that the crash occurs.

The testing server is setup correctly (ASP VBSCript) and I have done this several times withiout this result, so not sure why this is happening now.

Anyone seen this before or anyone have any idea what I might try to resolve the issue?
