Operation timed out when schema validate, returns errors when incorrect

Hi I’ve got a validating xml payload (CompanyIncorporation) however when I send it into the service I get “The operation has timed out”, when the schemas are wrong it returns xml with the error, I’m guessing this may be related to routing but may well be something else.

http://www.nexuscl.com/output1.xml is my payload.

any help is massively appreciated.

I have now responded to this via e-mail.
