Tellicast error message Missing Key

diogenes1@...
 

Hello all,
Suddenly my BAS setup is not working the error message thrown up by tc-cast-client is "Missing Key" followed by a five figure number which is variable. I have not removed the USB Key  from its socket on the pc and at present it is showing the usual red light. Can anyone offer advice.
Regards Peter
