A couple of months ago, I reinstalled Windows and all my programs on my laptop. Last week was the first time I used the coach since. When I tried to bring up VMSpc, I got an error message "unable to load(?) paramtrs.dat". I reintstalled VMSpc and copied in a backup of my .scr file and the program came up with a few glitches; had my screen layout but no data from last use and the odometers had total historical info. Program ran OK for the day, but I had another error message, which I can't remember, on shut down and when I reopened the program I again had the paramtrs.dat message with no data and all gauges were "SPEED" only. If I try to create a new gauge, there is no gauge listing in the new simple gauge window only Road Speed. How do I get VMSpc working again? Bernie
