SDK Error! (Please Help Me)

[nick_t]

I made my first map after following a tutorial. Then I pressed "run" but it didn't work (SDK not set up properly). So I copied the .bsp into my counter-strike folder and it worked! Ever since this, I can't run the SDK again. I haven't deleted or moved anything! Any Ideas?

I get the following message when trying to run the SDK:

 

[commando]

got the same thing.

what u gotta do (which i did)

is restart steam. then go and click on "hl2" as u normally do to play it and it will "validate files" for u like an update *that is what i got*

then after that sdk will work fine
