Can't enable an addon I have installed an addon Space engineers modding addon, but cannot check the box to enable it. I get this error on the console:

fake_module: addon missing 'bl_info' gives bad performance!: 'C:\\Users\\Besitzer\\AppData\\Roaming\\Blender Foundation\\Blender\\2.66\\scripts\\addons\\install.py'
Error reading file as UTF-8: C:\Users\Besitzer\AppData\Roaming\Blender Foundation\Blender\2.66\scripts\addons\release_scripts_wings_import.py 'utf-8' codec can't decode byte 0xc4 in position 26: invalid continuation byte

this part of the error message appears multible times in the console:

fake_module: addon missing 'bl_info' gives bad performance!: 'C:\\Users\\Besitzer\\AppData\\Roaming\\Blender Foundation\\Blender\\2.66\\scripts\\addons\\install.py'

Anyone knows how to fix this?
Looking at your Console log, it seems pretty obvious that you are using Blender 2.66. The addon (as stated on the SE Block Tools homepage) needs Blender 2.75 or later.
