Norton Internet Security 2010 ceased working after System Restore

Dear All,

 

My Norton Internet Security 2010 stopped working after a System Restore. I had to do a System Restore from Windows Safe Mode (I use Windows 7) because my laptop started blue-screening at startup today. I restored my system to two days ago (January 19), and my Norton Internet Security no longer works. Is there any way to fix this? I don't want to go out and buy Norton Internet Security 2010 again.

 

Sincerely,

 

Matthew Davis

 

PS: I have tried re-installing NIS 2010, however, the product key is no longer valid.
