VVP not updating

Hi
I use VVP with my WD and Davis VP2. In the last few weeks I have noticed that if WD stops for some reason and I start it again after a few hours, VVP starts to download data from several days ago, but I cant see the missing data, WD shows data only from the time I started it again, for example today (Dec 11th) WD was down for 3 hrs, we had rain all day, the station shows 42.2 mm of rain but WD shows only 32.2, although when I restarted WD , VVP showed like it was collecting the data. (Hope I made myself clear).
Any ideas?
Thanks
Eli

I had this happen recently double check your time on the console vs the PC. even a minute seems to screw it up.

Thanks, that was it

I nearly always get the data download from several days ago with weather display and I can always see the data as well. No other programs are effected and work fine just weather display and vvp have some issues. The time in my case is correct on both the pc and the console.
