Can't get Marlin 1.1.x to compile (no replies)

Everyone,
I can't get Marlin to compile. I've tried both Arduino IDE 1.6.8 and 1.8.3. I've downloaded a clean copy of Marlin 1.1.x Release version and the only modifications I've made to it where my stepper motor values since I upgraded to DRV8825's when I bought it. I'm running on a win 10 system.

I keep getting the following error when I try to compile and validate:
==================================================================================================================
Marlin:1: error: expected unqualified-id before '.' token

.

In file included from sketch\MarlinConfig.h:26:0,

from C:\Users\XXXXXX\Desktop\3d Printer\Release Firmware\Marlin-1.1.x\Marlin\Marlin.ino:32:

fastio.h:139: error: 'WaveGenMode' does not name a type

} WaveGenMode;

exit status 1
expected unqualified-id before '.' token

Thanks!
