I see what you mean, it is now giving me a blank page too.
What they wanted you to do was uninstall dreamweaver and xara then reinstall dreamweaver follwed by reinstalling xara.
Just to let you know I have had it with places that don't offer phone support. The lesson that I have learned is that I will not purchace anything on line, any more, that does not offer valid tech support.LET THE BUYER BEWARE! Be sure that you checkout support before you buy!
