Skydrive website cannot connect to my Windows 8 PC

I have set up my skydrive account and downloaded the app to my desktop.  When I open the app, I see the main screen that shows the files in the skydrive but no icon appears in my taskbar.  When I try to access my PC via the skydrive website, I get a message stating "sorry but skydrive can't connect to your PC."  I only have one pc linked to skydrive and it is my home pc.  I have tried uninstalling and reinstalling the skydrive app on my computer.  Sometimes when I first reinstall I see the icon in my task bar and am able to make sure that "let me use skydrive to fetch any of my files from this PC" is selected, and I am also able to access the pc from the skydrive website.  However, as soon as I restart my computer, the skydrive icon no longer appears on my taskbar (even though the app is running) and I can't connect to the pc from the skydrive website.  I have reviewed several other posts that discuss similar issues but none of the solutions offered in those posts has helped me.  I would appreciate some advice on how to fix this problem since I would like to be able to retrieve files from my pc using the skydrive website.  Thanks.
