windows live mail going online

I accidentally clicked on the "go online" icon on my Window Live Mail task bar. When I ckicked on it again to go back online, I kept getting a window saying I was working offline, and asking if I wanted to connect to the internet. Each time I responded yes, I just kept getting the same window again, asking the same question. I now cannot send or receive emails.

I tried turning my email off and on, then I tried rebooting my computer, but the status didn't change. How do I get back online? My internet connection is still working, obviously.

Thank you
