For me, it’s the same thing. Since the update, the launcher launches, there is written launch of the game in progress (1 sec up to 30s max) and then either it throws me the small rectangle and nothing more or it displays me “the game has crashed, error code 0x0”. Do you think they will make a patch quickly?
PS: I have not done all your manipulations, because I have a rotten connection and I do not know how to pass from D: or C: or vice versa. Do you think their fix or patch will solve the problem if I don’t do the reinstallation manips? If I reinstall the game, will I lose all my progress?
