ItsNotSleppy There is no images folder in t6 directory

I keep getting an error with tranzit, telling me that there's a problem with the first line of the code, and therefore cannot launch. Specifically, it says "unresolved external assign lowest unused character index with zero parameters in script", not sure how to fix it?

Do you need to be in custom games or something? I did everything but just booted in a solo game does that not work?
