Hi all, I Have win8 Pro version running and I recently updated to Wmc Pro using the microsoft provided upgrade function, The update was successful and I am running wmc + win8pro , which is activated to 180 days and has a 1000 rearms left.But the problem is after restarting the Pc after the upgrade Wmc will not open!.... I even tried running it as an administrator but it will not open! it doesn't give me any sort of error messages or something it just doesn't open!.. Please help me! Do i have any-other option other than installing the whole windows 8 again ?
