Problem using SOAP Toolkit 2.0 Wizard...

Hello Everybody,
        I'm pretty new to this SOAP & just started learning it .This is my
first question in this list !!!
        I'm using SOAP Toolkit to generate its .wsdl * .wsml files. I'm able
to generate those for most of the COM Dlls. Unfortunately its failing for
some COM Dlls. I'm not able to figure out the difference.

        Error is :
                                        Run Time error '35602'
                                        Key is not unique in Collection

        I get this error in a message box !!!

        Any idea about this or did anybody face this problem earlier ??
        What can be the reasons for this failure . Those DLLs for which its
giving this error are pure COM DLLs.
        Anyway i'm not able to solve this & would like to seek any **small**
hint from your side.


Thanks & Regards,
