Degree to projection conversion does not work second time.

I am using mapwingis in a windows form C# application. When button control is calling the plot GIS map method it works. But when it is called second time the following line keep providing projX = 0.0 and projY = 0.0.

AxMap.DegreesToProj(Long, Lat, ref projX, ref projY);
