I am taking the guess that "TeacherGaming" will use these kind of games to "educate" students in the classroom. They've done it with Minecraft already, so what will we do?

I installed the update, but now Portal 2 doesn't work anymore. It keeps showing an error report regarding a failure to locate the opening menu. How do I fix this?
