How can I call a web method from .net compact framework without getting an exception

When trying to call a web method from the .net compact framework I get the following (useless) exception in the debugger:

An error message cannot be displayed because an optional resource assembly containing it cannot be found

I get a slightly differently worded error on the mobile device, but it effectively says the same thing.

The 开发者_Python百科web service works as I've tested it in normal .net

I'm using compact framework v2.0, but I'm also tried creating a simple project in v.3.5 to test my problem - I've spent a while trying to solve this - most solutions & .Net tell me install the cab file called (for v3.5) netcfv35.messages.en.wn.cab (and for v2.0 either) system_sr_enu.cab and system_sr_enu_wm.cab

First I don't know why when I call this web method I am getting an exception in the compact framework when it works on normal .net (it only returns a simple object that has some string and integer properties). Further to that, I can't work out what is wrong as the exception doesn't display properly. Does anyone have any information that would help me? Thanks.
