Well here's the syntax of the AJAX I'm using on one of my own pages, which works fine for me:

JavaScript

var xml;
var fetchError = false;

$.ajax(
{
    type: "GET",
    contentType: "json",
    async: false,
    data: { someVar: 'some value' },
    url: "WebService.asmx/putStockplanFile",
    success: function (msg) {
        // store message returned by the request
        xml = msg;
    },
    error: function (msg) {
        // set a flag to indicate request returned an error
        fetchError = true;
    }
});

So why not give that a go first to see if it makes any difference.
