So the only files that are in the config folder are
config.default.json
sounds.default.json
configmodel.json
I tried removing each one separately and I still get the same javascript error.  When I remove the config.default.json file and try to start AGS; the file pops back into the config folder automatically and displays the same javascript error.
  
I am just looking to get AGS running in its default state.  I am not trying to run any non-native emulators.  The config.default.json file is posted below.  Thanks!!
