IRFFB closes then can't be opened

[CKPellatt]

This seems to be an on going issue. I downloaded VJoy 2.1.8 39, installed then downloaded iRFFB v1.4.2 (latest version) and installed. I then setup VJoy and opened iRFFB. I made some changes and then launched a test session in iRacing. Once the session loaded, iRFFB window closed and can't be opened again. How do I get around this?? Without uninstalling everything and starting again??
