I can't update my firewall.

My internet work fine.
Some info about my settings firewall:

Firewall Security Level:Custom Policy Mode;
Defence+:Save Mode;
Configuration:Proactive Security.
The version of firewall is:3.5.55810.432

Thanks.

Have you tried more than once? My configuration is Optimum security and I’ve never had a problem. Perhaps you could try with firewall and D+ disbled.
