I only Imported 3D Game Kit.. but some errors occurs..TT

hello. I use unity this first time, and i try to study for engine. So.. I found the '3D Game Kit', and I use it my practice...

but, When I completed import that template, my engine consoles shows some errors. I'm not use any function that just imported that '3d game kit'..... if the player mode is started, print the message 'All Compiler errors have to be fixed before you can enter playmode!'.. that sounds me crazy....... hah.......................................T _T

How can I resolved that problem....? please, somebody help me...
