I just bought Digimoto V to go with my OBDPros ELM327 scantool to have gauges and charts.  The main screen activates and I get readouts but I can't seem to get the other tabs like guages and charts to work.   What am I doing wrong?  I'm running a Compaq AMD laptop with VISTA.  I've tried limiting the selected  sensors but that doesn't make a difference.
