Dreamweaver MX lock up (Need Help!)

Hi,
I have am using Dreamweaver MX to create several different web sites.
The problem I have is that when I try to connect to one of the web sites the
program locks up and I have to close it down and start over. On this
particular site I have yet to connect with out it locking up. I am trying
to connect to a site hosted on bizhosting.com. The other sites all seem to
work and are on other host servers. I have contacted bizhosting.com and
they of course tell me that I have all of their information set up correctly
and the problem is with dreamweaver. Has anyone else had any problems
similar to this and if so are their any solutions that would be helpful for
me?
Thanks in advance,
James Liston
