“this app can’t open” with my windows live mail tile ..

I'm thinking could be related since I connected to Skype?  Which was just these last few days!

Is my only others option, reinstall? =/ maybe corrected..

I'm getting "this app can't open" with my windows live mail tile .. the tile has changed colors to a light blue shows a number.. but unable to open as of yesterday evening.. instructs to go to store where I check for update, not needed and license sync, which is fine as well ..
