It should work if you have your X3 Pro properly connected via usb. Run Line 6 Monkey to make sure that the required driver is installed, that it detects that your X3 Pro is connected, and that it detects that Pod Farm 1 is installed. If any of those are not detected by Line 6 Monkey then you have an installation problem of some sort.

For newer versions of Pod Farm you would also have to run Line 6 License Manager to complete the authorization. I'm not sure if this now applies to older versions as well - maybe worth a try.
