CCS4.2运行串口程序出现问题

我原来用CCS3.3,现在改为CCS4.2，导进CCS4.2以后，其他工程都好好地，只有串口工程有问题。
运行时弹出对话框：

我感觉是CMD文件的问题，可是CCS3.3没问题。
我换了以后，不出现这问题，可是有新问题。
加载程序后，程序不是跳到MAIN函数，而是其他地方，如图：

而且运行也不对。
原来的CMD文件如下：
/**********************************************************/
/*                                                       */
/*       LINKER command file for LEAD3 memory map    */
/*                                                       */
