Hey, I was trying to set up the autosplitter, following the steps in the readme perfectly. But, it does not work. I can not activate it, saying "there is no autsplitter available for this game" after I installed the auto splitter. how to I fix this?

Hey, I dont have a very powerful PC, lags when ever I load new chunks. If there is any peformence mod that is allowed, please inform me on it. Thanks for reading my question.
