Failed to start Anima: Gate of Memories

The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the '/home/linuxusr/GOG Games/Anima: Gate of Memories/game/GoMLinux_Data/Managed/mono/2.0/mscorlib.dll' directory.

Fix:
As stated in the last line, "mscorlib.dll" should be installed in '/home/linuxusr/GOG Games/Anima: Gate of Memories/game/GoMLinux_Data/Managed/mono/2.0/mscorlib.dll' directory. Hope, this helps someone out there who has the same problem. :-)
