No Anti-Virus Protection

Norton 360 for Mac
1

Hello

 

1) Norton 360 loaded and works okay on Mac-1 (new Mini w/ Fusion and OS 10.8.3)

 

2) Norton 360 loaded okay on Mac-2 (4-yr old Mini w/ OS 10.8.3), but cannot enable Virus Protection.  Scan engine problem even after running Update.

 

3) If I uninstall and reinstall Norton 360 on this machine, does it count as another installation (with 5-device Norton 360)?

 

4) With 5-device Norton 360, does loading 360 both as Mac and as PC (in Bootcamp) on SAME MACHINE count as one installation or two?

 

Thanks
