I have a problem. I can't upload any modification to my minecraft launcher because the information that I wrote in the topic name pops up. I've been tired of it for about three days, I was looking for information everywhere on Google, but I didn't find it. My launcher looks like this: Po wejściu w minecrafta wyskakuje mi taka informacja: I am asking for help, I really care about it!
