Test Sample shows blanks screen

[Kr3m77]

I'm running Tilengine 2.9.0 on Windows 10 Pro x64.  I compiled the following code listed on the Github repo's README.MD file and am getting a blank screen when I run the app from the samples folder.

Code:

#include "Tilengine.h"

void main(void) {
   TLN_Tilemap foreground;

   TLN_Init (400, 240, 1, 0, 0);
   TLN_SetLoadPath ("assets/sonic");
   foreground = TLN_LoadTilemap ("assets/sonic/Sonic_md_fg1.tmx", NULL);
   TLN_SetLayerTilemap (0, foreground);

   TLN_CreateWindow (NULL, 0);
   while (TLN_ProcessWindow()) {
       TLN_DrawFrame (0);
   }

   TLN_DeleteTilemap (foreground);
   TLN_Deinit ();
}
