this may be a simple issue of, you need to go to the toolbar at the internet screen and go to the "file" button and uncheck "work offline" (if it says that you are.) if you are using a high speed connection, it may also just be that the service is not working at the time, on my computer it occasionaly says that there is no connection even when i am plugged into the wireless router or high speed connection, this happens with all the computers in the house, and i just have to wait a while and the problem just goes away.
