NIS 2012 wont start, open!

Hello all..

 

I've just purchased NIS 2012 recently. I installed the product and it ran fine for a few days. Today all the suddent it stopped working. says all protections turned off! and internet toolbar says licnese expired! and it offers to fix the problem but nothing happens when i click on it! when I double click the icon on desktop and notification bar northing happens, wont start, open!

 

I tried uninstalling & then reinstalling, but didnt solve the problem. I ran malwaresbyte scan, emsisoft scan but no suspecious files, also spybot, all clean. i also ran trend micro online scan and it was clean!!

 

please I need your help..

 

Thanks a lot
