When I install the skydrive desktop app it syncs with no problems but the next time I turn on my laptop it doesn't sync and I can't see any way to log in. The icon then doesn't appear in the toolbar though I have customised it so that it should show. The folder is present but it is very much an offline folder. The only way I have currently found to make it sync is to uninstall and reinstall it. Obviously this is annoying and impractical. What would you suggest?
