Having issues with my MX-900 and MSC-400. I think it might have something to do with updates to the software and/or firmware. The system has been working well for about 3 years. I recently update the firmware on both units and made some changes to the software to accomodate new devices. The macros work on the MSC-400 when I test them through the front USB port but I can't seem to get the remote to trigger the macros on the MSC. I'm not new to programming and I've spent hours troubleshooting this. I've re-loaded everything the way it was when it was working with the exception of software and firmware version updates but I get the same result. Any suggestions out there for me before I lose my mind?
