I have just try it.. It ddidn't ask me to reboot.. I did reboot but it does not work.Click on network+ in settings and that will ask you to reboot, then it'll work fine, it happened me too, they must be linked
I have already done that.. Do you have 8.1 Update 1 with cyan ?Just checked. Never used it but it opens for me.928. Maybe you want to reinstall it.
Change your date to 2114 or something year. Try to open Call+SMS it will tell you to uninstall it. Do it. Then fix your date and reinstall it
