Thanks Ricco for your respond. I did what you suggested and it still do not work. Here is what I have in my set-up:
My polars- Collected points: checked
server: http://www.vrtoutoulz/velux/winds
Polars: http://vrtoutoulz.fr/polars/vrt_full/velux_pro-full.csv
MyPolars: http://vrtoutoulz.fr/polars/vrt_full/velux_pro-full.csv
Interpolate windspeeds: checked
boat speed factor: 1
Now when I click on SET I am getting Info: File C:\Documents and Settings\Owner\My Documents\vrtool\vrtoutoulz.fr/polars/vrt_full/velux_pro-full.csv not found or error in file
I just dont know what to do anymore. And it did work perfect at clipper races ...go figure.
Again the problem: when download from Firefox all is perfect. When I choose Draw route tool and then click anywhere on the chart Speed and VMC in Boat Attitude is zero till next download. Dont know what else to say about it. What I am doing wrong? Thanks for any help.
