If the transport on RAVEN has stopped functioning please review the specific setup procedures for the DAW you are using. A DAW's control surface and MIDI preferences can be reset for a number of reasons.
If you have followed the setup procedure and the Transport is still not functioning please close your DAW, RAVEN and V-Control Pro. Launch V-Control Pro then launch your DAW and then Launch RAVEN.
If your issues still persists please open a support ticket. https://slatemt.zendesk.com/hc/en-us
