[WriteLog] Can't read from radio

[Gary Senesac AL9A]

OK, it's officially panic time.  Just upgraded to 10.42C and now I can't seem to get Writelog to poll the rig for band, frequency, mode, etc.  Had it working before with 10.39C and think all the connections are ok.  DXbase polls the rig ok with the same connections.

IC756 Pro, CT17, Rigblaster Plus
Compaq Presario notebook, Rig control on Comm1

Can key the rig ok with the soundboard DVK, but can't get Writelog to find the radio.  What setting did I forget to turn on?
