am not sure what this error really means, any ideas? Help is really appreciated!

It is very possible that your WSDL is malformed. Or, the WSDL may contain features not supported by the webMethods version that your are using. Try validating your WSDL with a WSDL validation tool. Try importing your WSDL into a test tool such as soapUI and see if the tools finds your WSDL to be of valid form.

Also IS can’t cope with circular imports.
The wsdl importing and xsd1 which imports xsd2 which imports xsd1.
Other validation tools may find this OK, but IS will fail.
