RFX error

Hi, I am seeing this error in the event log.
Anyone that can understand what is wrong?

RFXCOM Error Error in plugin execution runConcurrentThread:

Traceback (most recent call last):
File "plugin.py", line 224, in runConcurrentThread
File "/Library/Application Support/Perceptive Automation/Indigo 6/Plugins/RFXCOM.indigoPlugin/Contents/Server Plugin/RFXTRX.py", line 1687, in startComm

<type 'exceptions.TypeError'>: a float is required

RFXCOM Error plugin runConcurrentThread function returned or failed (will attempt again in 10 seconds)

regards

I see that Indigo 6 is in the error message. I am running indigo 5. Is this the reason for this error?
