This happens, at least in my case, when trying to load patches with cabinet simulation turned off ("no cabinet" selected on the Pod x3 live). What I do is save the patch on the X3 with a random cab selected, then load it in Gearbox and use Gearbox to turn the cabinet simulation off, then export it back to the X3. This way, next time you load the patch in Gearbox it shouldn't produce the error. Hope this helps and sry for the late reply. EDIT: In the list of cabs on the X3 Live there are 2 "no cabinet" options listed (one following the guitar cabs and another following the bass cabs), only the latter produces the error, if you select the first "no cabinet" it shoudn't produce the error either.
