Steam DLL Isn't Worthy Of Our Trust On Line (#)?

[K737]

I keep getting this error, and I have just bought Garry's Mod today. Completely legit.

And if the fix is complicated (If there even is one), I need step by step instructions. I'm not yet very educated with computers.


And I don't want to hear "Then maybe you should have bought the game" because I DID buy it. I say this because I have seen other topics like this (on other websites), and this is a couple of the responses.
