My Windows Live is suddenly not allowing me to compose and send messages.  I checked the forum and found a suggestion to be sure Net 3.5 was active.  When I checked it, it shows only part of Net 3.5 working, but I don't know why--or even if this is my problem.  Can I uninstall and reinstall Windows Live without losing my settings?  Is it possible that a recent Win 10 update may have corrupted Live?
