Dreamweaver cs5 Live view

Hi, I would like to use Dreamweaver CS5 to edit my WordPress site on a localhost. I have set up a testing server and everything appears to be fine but live view is not working. When I press live view button it gives me white screen. On localhost everything works fine and the site and server specs are fine. I am on a Mac and I use Xampp 1.7.3.

Thanks.
