I'm very sorry you had this problem. Can you tell me exactly what error you have? And have you copied the exact wording for this file and the other one that can cause complications as well?
Your English is fine!
Did you copy and paste the file exactly? Or did you type it in? Some keyboards don't have the é in Pokemon, which is what causes that error, so double check that e. If it still doesn't work, maybe you could try another computer? If it still does not work, then I'm very sorry, then perhaps it is best to try to contact itchio support for a refund. Apologies for the inconvenience caused!
