I was adding a new bluetooth device to my computer, when I restarted, now when I click on devices and printers, I get a blank page, the green progress bar slowly crosses the address bar all the way across then just sits there, and the page is blank. The network page is also blank. This has happened before but it did not take long to correct itself, if nothing else if I restarted again then that would fix it, but not this time. HELP, what is causing this, and how do I fix it? See attachment for screenshot
