Log4OM

I had my live logging working but now it's not sending the files from Fldifgi to LOG4OM.Since I reset up both programs,I can't get the logs from fldigi to log4om.But Log4om can log to fldigi?I tried saving the configuration setting in the config dialog menu under Rig control menu>CAT(rigcat).I set it up for com port and baud rate but it gets changed after reopening the program.
Any suggestion?
Thanks Rich
