usually when it crashes in the middle of creating the pages it is because of a memory leak.
try closing the Files and server behaviors panels before running the wizard to prevent the issue.
the downside of using the Dreamweaver insert and update behaviors is that they can only use form variables for getting the info to store in the database.
DFP creates a variable when the file uploads called server file name which contains the name of the uploaded file.
DFP does not work with the Dreamweaver behaviors because of this limitation. you need to use the Data Assist insert and update behaviors when using DFP.
