MMTTY not keying radio

Jay Laferriere

I had everything on MMTTY setup on my computer to key my IC7300. I followed steps from YouTube videos. It was working just fine. Then I jumped off for a little bit and got back on. The program would not key my radio. Yes I changed bands from 20m to 40m but it would not key. Then I switched back to 20m and it seemed to work, but was glitchy. I reset my radio, reset my computer and nothing changed. It just stopped keying the radio. Help please?
