Boot-Time Protection Won't Stay On

Hey there, 

I'm working with Norton Security Deluxe here, and I'd like to turn Boot-Time Protection on, so I navigate through to settings, set Boot-Time protection to "Aggressive" click Apply and Close. Not a second later I'll open the Antivirus settings to see that Boot-Time protection is set to "Off" once more as if the change is reverted immediately. It simply won't stay on. (Same thing when trying to set it to "Normal".) 

I've run LiveUpdate repeatedly, as well as tried running NS as Administrator and still no dice. I'm hoping to find a solution, as I've scoured the internet looking for someone experiencing a similar issue to find naught. I should also note I'm on Windows 7.  

Any thoughts would be much appreciated. Thank you!
