Unable to upload MB-SID Test Tone Program

[JaseM]

I'm having some problems uploading code with my Mac. I'm running Leopord, MIOS Studio 9.4 with Mandolane and I'm unable to transmit data. I've tried an Audio Kontrol 1 and a Midisport Uno, and neither are able to send Hex. When I tried to do a sysex loopback test with my Audio Kontrol 1, I couldn't get MIOS Studio to recieve any data. I've tried the units with other programs and the MIDI works fine. I also double checked the connections in MIOS Studio (MIOS OUT to MIDI OUT, MIOS IN to MIDI IN) and they are also correct.

Is there anything else I should be trying?
