Sitebuilder offline and cant get it to connect so I can publish

I have recently downloaded sitebuilder on my Win7 computer, updated a page and saved it. But it wont let me publish the page. The bottom right corner says offline. How do I get it online? When I click publish it says to connect. I click connect and it says I am not online. There does not appear to be a link to tell the program whether I want to work online or offline either. I went to log in thru Firefox and it says I may need to update sitebuilder, I tried that and when I click on the downloaded file it just opens sitebuilder. I really need to publish this page. Help please??
