Can I use the same version of probeManager and IPSet as I used to use with the previous versions of firmware on my sensorProbe?

No, we have we updated both of these utilities (probeManager and IPSet), so that when you run the new firmware update it will load the correct code for that particular type of unit from the main update file. You can download these updated utilities from our web site by logging in with your units MAC ID at the same link mentioned above.
