Breaks when opening

[CRAZYKOKEBROZ 64]

Whenever i open modelbench, i get this error message saying things like 

___________________________________________
############################################################################################
ERROR in
action number 1
of Other Event: Game Start
for object app:

Cannot load buffer file
############################################################################################
--------------------------------------------------------------------------------------------
called from - gml_Script_buffer_load_lib (line 5)
called from - gml_Script_json_load (line 7)
called from - gml_Script_load_settings (line 5)
called from - gml_Script_startup (line 61)
called from - gml_Object_app_Other_2 (line 1)
 

And then when you click ignore 3-5 times, it then doesn't open. Why is this happening, and when will model-bench beta finished? Because I have really cool ideas to make with it.

Anyway, Is there a way to fix this? It would really help if you guys have an answer.
