Hello, I am having trouble adding the system to my project. When I try to get the dialog box to 
appear on the screen, a null pointer exception appears on line 123 of the MSG_Parser script and to 
be honest I can't understand what func level_root () does (more mainly the "(" level_root "part) ) ", 
because there is no" level_root "tag in the sample project as far as I can see). I managed to find that 
that function was the one that returned null, but I can't find a way to fix it. If anyone knows what may 
be going on, I will appreciate the help.
