Thrilled to have a new Surface but I cannot download the apps. When I click on "install" it waits a few minutes and then says "unable to install try again or cancel. When I click off everything the "Device set up dialogue box" is revealed. "Installing device. Please wait while set up installs the necessary files on your system, this may take a few minutes" It has been 24 hours and the same small amount of it has been installed on the "bar". Please help. I have tried this multiple times over the past few days with the same result. I have tried installing Skype and a few others from the App store.
