No longer collecting data from Davis VP

My WD has started playing up and no longer getting data from the Davis VP2 serial data logger. I have tried redoing the setup, the logger is seen on Com3 but the data is not being collected even if I try a manual update.

I downloaded and installed the latest v 10.37S Build 79 and everything started working again but all the history had gone. So I closed WD and re ran it but this time the history was back but no data logging. Rebooted the Win10 PC and WD started but with the historical data and no logging. What is going on and can I get back to retaining history and data collection? System has worked perfectly for years hither too.

Edit: just noticed I seem to have two different versions depending on what I click on.

maybe check your short cuts

Yes, I found I had two wdisplay folders on different drives. Now resolved but how do I move the history (max/mins etc) from the old non working installation to the new one?

they are stored in the wdisplay.ini settings file

Thanks - sorted!
