Problem with Dreamweaver and site management

So I’m using Dreamweaver 8 – and I think the Site Management feature is very valuable especially if I’m running a testing server locally.

However, I’ve been having a problem lately. I’ll be working on a page and for some reason when I go to test the page, it won’t put the last edited version on the testing server (which I’ve set up in Site Definitions as Local/Network). So I can’t test any changes I’ve made. Anyone ever have this problem or know how to fix it?

Note: Now I don’t mean the Remote server…which is my web hosts server. That uploads fine.
