Terminal log from `wine AC4BFSP.exe`

After clicking the "Play" button in Ubisoft Game Launcher (or launching `wine
AC4BFSP.exe`), a window pops up informing, that the game is starting, but it
disappears and the game doesn't launch. I don't have the Steam version, just
the Uplay one.

I've set Windows version to XP, wineprefix is 32-bit.
Wine version will probably be visible when I post this, but I'm going to
mention it just to be safe. Using Wine 2.20 staging
