As Jason said:
as for Data Bridge crashing, make sure that you have the latest 1.1.3 version installed.
if it is still crashing, some things to try are:
-Disable the preview
-Close the Files panel and the server behaviors panel before running any wizards.
Close everything you don't need running. Only have one page open in DW, ie, the index page of the folder where you need to do DA. Close all other items on DW. Take your time! Don't rush. Pause. Pause. If you let each step have a bit more time, you'll reach the end of the process.
As I've been enlightened by WA, DW has a limited amount of memory and DB needs room to work. You can't increase DW memory, so you need to strip down using its resources.
