Windows 7: File Sharing and Homegroup Sharing Problem

Hi,

I have been going crazy trying to get my PC to share files with a couple of laptops.
I am running Windows 7 64 Bit and the laptops are running Windows 7 64 bit and Windows XP.

I have enabled file sharing but The Windows 7 Laptop keeps giving me an unknown error when trying to join a home group after I have typed in the password from my PC. The XP Laptop doesn't even find my PC on the network. Files sharing worked fine using my old router but I have just updated to a Virgin Media Super Hub and think it's either something to do with Anti-Virus Software blocking connections or the security setup of my Virgin Super Hub.

Jimmy PC is the laptop I am trying to share with as you can see from the picture. Are the gaps in the connection of any significance to my issue? I can share my internet connection with it with no issues but I can't share files.

Any help would be greatly appreciated.

Thanks

Chris
