I recently discovered that my FBV Express (the original not the MKII) is no longer working with my POD XT.  I have tried multiple ethernet cables and none work.  The FBV Express shows the current channel that I'm on with the POD XT (when I'm on 1C for example, the FBV shows that I'm on the C), but when I push a pedal on the FBV it causes no change to happen with the POD XT.  I've tried to recalibrate the FBV with no change, and have also tried to roll back the memory on the POD XT to see if that was the issue and still nothing.  Wondering if anyone has an idea of what would cause this.  I know the FBV Express has worked because I have used it within the past year.  Thanks for any help anyone can give me.
