  1. I tried this and it doesn’t work. It’ll load up the game but then my whole screen just turns black and the game shuts off. It doesn’t even stay open long enough for me to get into a match

  2. You are amazing! Moving it to a new folder worked like a charm!

  3. i did that and it says i do not have the correct version of it

    1. Try reinstalling the launcher and doing all again.

  4. Thanks a lot that worked !

  5. Worked! Thanks my guy!
