MPLAB IDE写P18点灯测试

求大神指导用MPLAB IDE8.89的MPLAB C18 （mcc18.exe)写一段LED闪烁测试，但是每次编译时都出现如下提示，请问该如何解决。而且每次都提示要不要再开一个软件测试，然后需要点击否，最后出现failed to load E:\PIC\test\test.cof的小窗口。这样的话就不能够用PICKit2来仿真，烧录了（PS. 用范例的HEX文件可以烧录）

程序如下：
#include "p18f87j11.h"

void delay(int i)
{
        while(i--);
}

void initial()
{
        TRISD = 0x00；
}

void main()
{
        initial();
        while(1)
        {
                PORTD = 0x00;
                delay(2000);
                PORTD = 0xff;
                delay(2000);
        }
}

如果使用MPLAB SIM编译则出现以下提示：

不了解，表示没遇到这种问题。

编译信息没有错误呀，PORTD是不是有其他的默认用途?
