MX2004 Dreamweaver serverbehaviors function issue

Hi

I have started having problems with an ASP site I have been working
on. I get a warning "The dynamic data script does not define the
findserverbehaviours function" when I open any dynamic page that I am
editing...Also when I attempt to add another dynamic element such as a
dynamic list, I get other warnings telling me that there are other
issues : " Java script error"Dynamic select list" reference error
initializeUI is not defined".

When I close the program down I have to use windows task manager to
close the program down as it hangs up.

I am using version 7.0.1 MX2004. I haven't had any issues like this
before and would be really greatfull if someone could help me out!....
