When I create a fax,return error:Server was unable to process request.. 0x8004023b Invalid Operation performed. Platform

This is my code:

CrmService service = new CrmService();
activityparty party = new activityparty();
Lookup Lookup1 = new Lookup();

if (!IsPostBack)
{
try
{
service.Credentials = System.Net.CredentialCache.DefaultCredentials;

// Get the current user.
WhoAmIRequest userRequest = new WhoAmIRequest();
WhoAmIResponse user = (WhoAmIResponse)service.Execute(userRequest);

service.CallerIdValue = new CallerId();
service.CallerIdValue.CallerGuid = user.UserId;

I search the error code.It seem a Loophole.
"You must have Update Rollup 2 for Microsoft Dynamics CRM 3.0 installed to apply this hotfix."

But there are not Japanese version of Update Rollup 2 for Microsoft Dynamics CRM 3.0.
How can I do?
