Ep2 content for Source SDK

I own the Orange box, and have Ep2 installed, but the only game in the orange box, when I load up Source SDK is team fortress 2.

I wish to use episode 2 content, any way to fix this?

load up ep2 once to the main menu, close it, restart SDK, press “reset game configurations”.

Did you mean “Refresh SDK content”?
I did what you said twice, and it failed to work.

Edit: I got it to work, thanks though.

This is a common problem faced by new mappers. It’s even around those who are experienced, but had to reinstall steam to another computer.
