Error in compile

[Asknoone]

error! unable to load c\program files/valve/steam/steamapps/username/half-life2/bin/filesystem_steam.dll

What be the problem?
I assume its something mind numbingly easy and simple to fix, but I'm not computer oriented

Run Half-Life 2 and HL2DM first. Then try compiling. If not, check for errors in your installs. Otherwise, reinstall the SDK.
