EPG Help

[Jontos]

Hi. I have been trying for the longest time to configure my system to allow the EPG to update. I am using a new NForce 4 Ultra motherboard with ActiveArmour firewall turned on. Even with the firewall disabled I still cannot update my EPG. It appears to be unable to connect successfully to the server. I have a home network set up, with 2 computers connected to the net via a DLink broadband router. The internet connection works fine, and I've successfully set up the ActiveArmour firewall to allow certain ports to open for various other apps. However, I still cannot connect to the net through GB-PVR. I installed the program on the other computer just to test it to see if I could update the EPG and was successful. That PC is running WinXP with SP1, and windows firewall enabled. The PC I'm trying to run GP-PVR on has WinXP with SP2, but only the ActiveArmour enabled (Windsows firewall disabled).
My question is how I can configure the computer with ActiveArmor so I can download the EPG (I'm pulling it from ZapToIt). (what ports, etc. does GB-PVR require?)
Also, if I'm unable to get things running that way, I would like to know how I can update the EPG via the listings downloaded to the other PC? What files do I copy, and how do I install them onto the my PC?
Is there a simple way to copy the data from the net (perhaps using a small program) that I can do this at work if need be? (so no programs need to be installed, just run from a USB jumpdrive)

Thanks.
