Asp.net Webservice simple question

Hi,

I am new to webservices. I am trying to invoke a webservice in Asp.net. The information about the webservice can be found at http://hurricane.terrapin.com/soap_access.html.en

I have added http://weather.terrapin.com/soap/HurricaneService.wsdl to my webreferences successfully. In my code I try to invoke getCurrentStorms method and it gives me error. My code reads like:
************************************************** ************************************************** ************************************************** *************

Private Sub btnGetStormNames_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGetStormNames.Click

Dim aw1 As com.terrapin.weather.HurricaneServiceService = New com.terrapin.weather.HurricaneServiceService

Dim ws1 As com.terrapin.weather.StormResult() = aw1.getCurrentStorms

Dim stormRes As New com.terrapin.weather.StormResult

With lbStormNames.Items

For Each stormRes In ws1

.Add(stormRes.stormCode)

Next

End With

End Sub

************************************************** ************************************************** ************************************************** *************

When my code reaches the
"Dim ws1 As com.terrapin.weather.StormResult() = aw1.getCurrentStorms"
line, it fails with the following message:

************************************************** ************************************************** ************************************************** *************

The specified type was not recognized: name='StormResult', namespace='urn:HurricaneService', at <return xmlns=''>.

I would be really helpful to me if someone can point out what is wrong in my code.

Thanks
