Intralink 3.3, Internet trouble!

Hello

I've done a test install of Intralink 3.3 and Wildfire on a stand alone machine. This machine has its own modem,

When the computer is connected to the internet Intralink will not start. I click the Ilink 3.3 shortcut then nothing happens, As soon as I dissconnect from the internet Intralink fires up ok?

Anyone had a similar problem?

Thanks

Geoff
