I installed version 5.1.2 on my desktop PC and now the tool is not working anymore. It tries to authenticate for a couple of minutes and then I get a message "[9001] Time-Out requesting Data Requesting [WDC-AUTH] [1W]".

I then click "Register" and after half a minute or so I am in the application. But then every request takes many minutes and sometimes produces an error message.

No issues at all with my notebook which is still on 5.1.1
