So a LOT of people are having issues with this \ o /!
The only thing we can do is relax and wait for the tech ppl to fix it o/ hopefully it wont take too too long. o; But my guess from a highschooler thats planning in going into the tech field is that either:
A) A certain amount of computers recieved a corrupted file that is forcing the launcher to not open the game window, thus no directory for the launcher to grab at and pull open.
B) Certain computer models can not compute with the newest files or derderder it takes to run the game.
Hope it gave the techs some ideas o/
