MIDI Device Problems on PT 2019

[littletrainrec]

I'll start by apologizing if this seems like a rudimentary question. I'm technically inept enough where this has stumped me.

For many years, I've recorded with PT 6.x, 7.x, and LE, an Mbox2 interface, and a MIDI keyboard (a Casio WK-3000). I recently (finally) got a new laptop with Windows 10 and some processing power, so I subscribed to PT 2019.

It's great with mics and DI instruments, but I can't get PT 2019 to recognize the Mbox2 as a MIDI input device, and thus can't get any virtual instruments to work. I run MIDI-OX and it tests fine. I've tried reinstalling drivers to no avail. I've watched more YouTube tutorials than I'd care to admit. I plug the Mbox back into my old computer/PT LE, and it works fine.

I'm hoping that those are more knowledgeable about these things than me (which is probably all of you!) can offer any suggestions. I realize that my interface is ancient at this point, so this budget conscious musician is hoping it's not a compatibility issue.

A very sincere thank you for any thoughts.
