Build error in CCS Version: 5.5.0.00077

System Environment:
 . Windows 7
 . Code Composer Studio: v5.5.0.00077
 . SYS/BIOS: bios_6_35_04_50 @ MCSDK_02_01_02_06

I'm a beginner for TI Family development.
After setup CCS, MCSDK & NDK_2_22_03_20, I received the project files from another developer.
It has been built successfully in his computer.

But..
In my computer, there is no way to build the project.

Build result as below.

**** Build of configuration Debug for project TSTv0.01 ****

I think it must be configuration problem, but I don't know how I can fix it.

Thanks in advance..
