SpywareGuard LiveUpdate behind Proxy/Firewall

[Visor57]

Hi there, I'm having trouble with SG's LiveUpdate behind MS ISA Server. I'm not using the ISA Firewall Client on this particular machine. The LiveUpdate app manages to download the first file but then stops. It remains in this state until closed. I've attached a shot of the dialogue box.
Is there a way to configure the connection settings for SG? SpywareBlaster's update used to mess me around until I specified a proxy in it's connection settings...
