ProjectTemplateNotFound when create project from template(belong to other user)

When I create project from enterprise project template using PSI(project server 2007) which created and checked in to project server by another user,error occurs as belows:

System.Web.Services.Protocols.SoapException: ProjectServerError(s) LastError=ProjectTemplateNotFound Instructions: Pass this into PSClientError constructor to access all error information
   在 Microsoft.Office.Project.Server.WebService.Project.CreateProjectFromTemplate(Guid templateUid, String projectName)

the logs are as belows:

PSI: Project.CreateProjectFromTemplate
Undefined Attributes: PSError: GeneralSecurityAccessDenied 
Undefined attributes list: 3dee3fa0-1956-4b98-84bd-2259d5b8829c

The "CreateProjectFromTemplate" method is successful when the current user is the same as the user created the project template or the administrator.

I've already given the user the permission to openprojecttemplate and create project.

Can anyone help me solve this problem?

Thanks.
