Do you have another plugin - i cannot open your C2-project because C2 claims missing the "Scoreoid" plugin.
Some suggestions after a short look in the runtime:
#) Why do you init the instance-variables (or object-variables (?)) in line 70 outside any function? I suppose line 65 or 53 are better places for the initiation.
#) "blank grey screen and nothing works."
