hello guys, well since i've been forced to launcer, i cant play w/o it. actually my old laptop got fucked so i'm using the other one, whenever i try to login with launcher, everything works fine but in the end, i get this error.
Well i had same problem also, Idk. I just re-opened launcher and it worked fine for me.
You can also try re-install the launcher.
If some of those advices didnt worked then i can't help you unfortunately.
