Did this error throw after you customised/added your own kind of text event? I can't be sure without seeing your code, but I'd say it's because it doesn't have the right number of arguments for the "emotes" part. Make sure you fill all of the arrays with the same number of arguments.
If you're still having trouble, feel free to e-mail me your project at friendlycosmonaut@gmail.com and I can take a look.
