Does anyone know what this means? It suddenly came up when the radio was operating.

Flex 6600M, Windows 10, Smart SDR.

Smart SDR CAT (v3.2.39.3374) An unhandled error has occurred: The invocation of the constructor on type 'CATWPF.Main Window' that matches the specified binding constraints threw an exception.
Inner Exception: Critical error! Internal API error.

Followed by more lines of technical jargon.
The radio is still working ok but I no longer have the CAT icon come up on the task bar. My Writelog program still logs the correct radio frequency.

Thanks for reading, Mike, WM5DX.

    Hi Mike, Best bet is to do a screen capture of the error message and attach it to a help desk ticket.

    I opened a ticket for this.
