Unable to Activate License License in use; no more activations allowed (code=4)

My Maker licence keeps reporting this error after 1-3months of running fine. I'm using it to log my house water flow, so this happening is a bit frustrating since I now lose weeks/months of logging if I don't check on it regularly...

As mentioned, it activates fine, works for a period of weeks/months, and then I see that one day the trial has expired and my licence has expired :confused:
