Operating system win 8. I have been running my 2812 with HW Pro with no problems. Started running with VWS and was working well. In doing changes to VWS started not communicating with sensors. Checking around found I did not have currdat.lst . Did complete reinstall of both programs numerous times, ( I think that all traces of HW were removed, cleaned computer new downloads from Lacrosse )restart and reinstall still no currdat.lst. Reinstall creates HW in startup checking properties says it should be in C:\programdata.. Any suggestions now have it running with VWS on my Win 7 system
