After hours and hours of copying, swapping files etc. it appears something in the original VWS is corrupted and blocking the barometer because I did a clean parallel install of the basic system, cleared the Davis and the barometer works telling me the Davis is ok, VWS can receive and display barometer, but where is the corrupt file?
At this point I'm at a loss, it's not the dbase or today's .bin file, it's not any of the dll's on the root directory of VWS, it's not the VWS executable, so where? I really don't want to have to reprogram all the gauges etc., but maybe that's the end result.
