I'm running Norton Utilities only, and that is limited to its disk utilities and the protection center feature that monitors status of whatever firewall and antivirus - that is, are they there and working. Been doing since I first started using Blink with no ill effects. As I noted, there was no indication of a problem until the NPC icon displayed a red x.
I reintalled Blink 3.1 and things worked fine until it automatically updated and status went back to Reboot Pending.
I can start Blink manually, but the starting service window turns into a a error window: Blink Service failed to start (0x80040201).
I stopped the NPC service and had similiar results and error code.
