I recently installed NIS 2013 on my Win 8 laptop. Everything seemed to be fine however when I tried to launch Mail, Video, Weather, Messaging etc; all these apps didn't seem to work and would only lead me to a stalked screen or a blank screen. Internet is fine and IE is working. Funny thing is the Live Tiles still showing updates on new emails, facebook updates etc but those applications just won't run. Dose anyone got the solution for this issues? I only tried to disabled some of the features in NIS but they were not helping. Thanks.
