What leads you to believe that Support_Preferences is related? It has no code that deals with loading and doesn't act on your client at all. The reason you see any error at all associated with it is due to a empty file being created with that name as it's packaged with Glass.
I noticed that you have Blockland Glass as "System_BlocklandGlass(1).zip". You may want to fix the filename.
Your console logs don't show much. They don't show you doing anything, actually, besides starting the game and then the game closing peacefully. Both show that you're in demo mode.
