I have updated my ProfiLux II to version 4.0.1.0 and after doing so I am finding that the CLEAR ALL is no longer working as in the past. In previous versions you ran READ & SAVE to save your data and afterward you ran CLEAR ALL to begin a new cycle of data savings> This does not seem to work as in the past. Now after using the READ & SAVE the CLEAR ALL button is not active and cannot be used until there is new data added however if you run CLEAR ALL before you run READ & SAVE you will loose all of the currently unsaved data. Therefore the data cannot be cleared to start collecting for a new cycle or month.
