As far as I know, the device has been in the same port the whole time (I use a front-side port for my XMIDI). I can try to re-install and see if it works, but again, why does BIAB recognize it and RB/PTPA not?

Actually, let me rephrase that. RB/PTPA does recognize it, because it lists it in the list of available ports to use; however, after I select it, it then tells me that it is not available to me.

Finds and uses it fine on my Vista system, though. I wondered if it's the driver for XP (versus Vista); however, since BIAB works,then it seems that maybe RB/PTPA is reading the port differently for some reason. Maybe one of the PGMusic techies can weigh in here, as I'm pretty sure we won't be the only folks with this problem.
