Hi, hope someone can help me.

The game was working perfectly until this morning, just a couple of hours ago. When I closed it today, an error appeared, but it was the second time that an error poped up, and the last time nothing else happened. But this time, when I tried open the game, it just won't boot. It crashes upon opening.

I tried uninstalling and reinstalling the game. Restarting the computer. Removing the Disgaea 2 folder from /steamapps, removing the save files from /userdata. Removing the Steam application (not fully uninstalling it) and installing it again. Switching to beta and pulling out, as happened to https://steamhost.cn/steamcommunity_com/app/495280/discussions/2/1470840994975006711/

But nothing worked.

My specs are:
MacBook Pro (Retina 13 inches, beginning of 2015)
Processor 3,1 GHz Intel Core i7
Memory 16 GB 1867 MHz DDR3
Graphics Intel Iris Graphics 6100 1536 MB
