Xlife Error

When activating Xlife I get the following error in the log

0:07:19.038 E/SYS: | Error loading the scenery file:
0:07:19.038 E/SYS: | E:\Xplane 11/steamapps/common/X-Plane 11/Resources/plugins/X-Life/Aircrafts/OSX_anim/b737-300/anim.obj
0:07:19.038 E/SYS: | The scenery may not look correct.
0:07:19.038 E/SYS: | Please see the Log.txt file for detailed error information.

Any help would be much appreciated
