I am a DIY guy and have programed this remote before without issue. Got a new cable box, tossed all the old connectors and went to HDMI. I have gotten through naming devices and setting up the IR databases (all work under "test" mode from the MX Editor) however when I try to download to the remote I get
a Microsoft Error -

"MX Editor application has stopped working...windows will close the application..."

This only happens with the program I created. I can download the demo program without issue.

Asside from the obvious (create a new program and try again) I'd rather not waste the time if someone has any ideas as to what went wrong
