Using the Web Service References Tool 2.0 for sending and receiving complex data (arrays of objects)

Question

I used the tool about 3 years ago to create the classes for a webservice client to send or recieve arrays as complex data. Now  i have to update these classes, since there are additional informations, that have to be exchanged. When i use the tool now with the new wsdl-files, it does'nt create the classes for complex data (structur, IGCTMObjectFactory), but only one class for simple data. 

In addition i have to establish a new client, that sends an array of complex data and  receives another array of complex data. I tried to build the classes manually combining the client that sends an array with the client, that receives  an array, but I failed.

Can anyone help?  Has anyone a sample  of  how the classes are like  for sending an array of objects an receiving an other array of other objects?

Thanks
