have you checked any of the stickies above ?
They are there in response to the most common issues and I think yours might be one of them
Turning off your firewall might help you out here.
Is the install from a disk and if so have you updated to the latest version ? Version 3.3.0 Build 31

Make sure you add BFD 2's data paths in Eco if you can't find them.
