TMS320F28388D: usb_ex1_dev_serial.c Program will not compile.

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE, TMDSCNCD28388D

I am trying to get "usb_ex1_dev_serial.c" to run on a TMDSCNCD28388D development board.  I downloaded CCS and C2000Ware_26_00_00_00 onto my machine in all of the default locations.  I downloaded and ran "led_ex1_blinky" without any issues so I know I am hooked up correctly and my JTAG settings are correct.  However, usb_ex1_dev_serial.c will not complile as it cannot seem to find some of the #include files.  For example, the following is what I get on build:

"C:/ti/C2000Ware_26_00_00_00/libraries/communications/usb/f2838x/include/device/usbdevice.h", line 74: fatal error #1965: cannot open source file "include/usblib.h"
1 catastrophic error detected in the compilation of "syscfg/usb_structs.c".
Compilation terminated.

I have looked in the C2000Ware files and all of the mentioned files are present in the correct locations.  I think it has to do with the paths included in the C2000 Compiler>>Include Options settings, but I am an novice with CCS and don't know how to set it up correctly.  Any advice would be greatly appreciated.
