let me guess, it was the ultimate idea to replace the p.knights scripts with the demo ones and thus be able to get the one thing p.knights don't have?
you just need to create font.size and font.type or whatever they are called ~_~
meh just get back to the p.knights scripts it's not like the scripts are much clearer cause of the english
btw, this can also be because of a script you replaced and was done in the legal version, again it's those 2 lines, find them and replace the variables with 30 and "Arial" (size and type)
hope it helped, if not use the search button to find what are those variables they can be found in alot of legal-made scripts
