I have downloaded the PlaneShift-v0.5.1-x86.bin file.
And install them to /opt with default option.
After installation, there are short cut icon in my Applications menu.
I clicked the menu item of " Applications ==> Games ==> PlaneShift".
Then an opened window with title "PlaneShift Launcher" appeared.
And it will jump another dialog about update.
Whether I update or un-update, I would fail to play this game.
Oh, my god.
It's so trouble to play game in the linux operation system.
I am very appreciated with you who can help me.
Thank you!
