Unable to Compile C2000

Hi,
I was trying to exercise PWM operation for a C2000 operation. I tried to build but I am facing compilation issues. The build fails at compile step10 with a compilation error. I tried to run a LED blinker and received the same error. Do you have any idea why it’s not compiling?

Compilation failure
Blinker.mk:284: recipe for target ‘output_TI2837x_cpu1/Blinker_hal.obj’ failed
make[1]: Leaving directory ‘C:/Software/C2000/Blinker’
Blinker.mk:161: recipe for target ‘all’ failed

“Blinker_hal.c”, line 9: fatal error: cannot open source file “plx_hal.h”
1 catastrophic error detected in the compilation of “Blinker_hal.c”.
Compilation terminated.
make[1]: *** [output_TI2837x_cpu1/Blinker_hal.obj] Error 1
make: *** [all] Error 2
