Yup, it works fine now!
Btw, the Launch.sh script is both broken and unnecessary; All it does is set LD_LIBRARY_PATH to the local path and then runs the game's binary, but there aren't actually any libraries in the shipped package. But on top of that it can't even be run, because it's missing a hashbang at the beginning to tell the kernel what interpreter to run it with, so when you try to actually run it, you get "exec: Exec format error". So either delete the Launch.sh completely, or put #!/bin/sh at the beginning :)
Hope that helps!
