I need to see the exact URL you posted on the web site and the code including all parameters you are trying in the web service

I did my test with Round, Color: E, MinSize: 1 MaxSize:1 in the web site and in the WebService and I got the same results

Here is my code:

DownloadListings webServiceManager =

                        new DownloadListings();

                  //This must be done in HTTPS protocol

                  webServiceManager.Login("username", "password");

                  //After log in you will receive a encrypted ticket with your credentials. This will be used to authenticate your session.

                  //Now you can choose to change the protocol to HTTP so it works faster.

                  webServiceManager.Url = "http" + webServiceManager.Url.Substring(5);

                  DownloadListingsParameters setPatams =

                        new DownloadListingsParameters();

                  Shapes[] MyShapes = new Shapes[1];

                  MyShapes[0] = Shapes.ROUND;

                  Colors[] MyColors = new Colors[1];

            MyColors[0] = Colors.E;

                  setPatams.MinSize = 1;

                  setPatams.MaxSize = 1;

                  setPatams.ColorCollection = MyColors;

                  setPatams.ShapeCollection = MyShapes;

                  //setPatams.Markup = 120;

                  DataSet ds = webServiceManager.GetDiamonds(setPatams);

                  System.IO.File.AppendAllText(@"C:\\TestWithOutMarkup.csv", Excel.ConvertToCSV(ds.Tables[0]));

And the URL I posted in the site:

http://technet.rapaport.com/HTTP/RapLink/download.aspx?ShapeIDs=1&WeightFrom=1&WeightTo=1&ColorIDs=2&SortBy=Owner&White=1&Fancy=1&Programmatically=yes&Version=1.0

if you prefer to send me your code to my email you can send it to this email: Ahaliav@diamonds.net
