Source SDK Issue. Insight?

[Melon_Cat]

I have Source Sdk up and running with gmod, I can build and edit maps just fine, but the one thing I've had a problem with, is that when I spawn an enitity, such as, info_playerstart, I get the wonderful Red ERROR Object. This also happens with overlays, decals, and other things in that nature. Could somebody be kind enough to enlighten me with how i can get rid of those Error Signs, or at least show me a link where i can get those models?

Do you have HLF2 installed?
