Could not generate stub object - The element type "META" must be terminated by the matching end-tag "".

I am getting the following error message when I try invoking a webservice.

Could not generate stub objects for web service invocation.
Name: ProgrammePrivilege. WSDL: https://clientaccweb.reseaudistinction.com/CardHolderInfo.asmx?WSDL. org.xml.sax.SAXException: Fatal Error: URI=null Line=11: The element type "META" must be terminated by the matching end-tag "". It is recommended that you use a web browser to retrieve and examine the requested WSDL document for correctness. If the requested WSDL document can't be retrieved or it is dynamically generated, it is likely that the target web service has programming errors.

The problem is, the webservice is working fine, the application was working yesterday, the error message just appears after a couple of days and I have to refresh the service in the CF Administrator. Once I refresh it, everything starts working again. Anyone else got this problem? ANY help would be appreciated!

If you guys need my code anyway, I can attach it but like I said, everything works for a couple of days, then, out of the blue, it stops working so I doubt that it's my CFINVOKE that's the problem...
