Compile error

[TorQueMoD]

I tried searching for this error both on these forums and in google with no results, so I appologize if this has been posted before.

I'm trying to compile a model that I know compiled successfully before, but every time I run studiomdl I get the following error

Does anyone know what's causing this error and how to fix it?

Thanks!

Two things you can try...
1. Open up HLMV, and leave it open, compile the model
-OR-
2. Multi-step solution
a. run the game you wish to compile for, and exit that game.
b. copy every file EXCEPT TrackerNET.dll and TrackerUI.dll from that game's "bin" directory (ex. SteamApps\%username%\half-life 2 deathmatch\bin), over to your sourcesdk\bin directory, and try to compile.

I'm not sure what is causing this error but I think it has to do with engine updates. So far one of these two fixes have helped most people.
Good luck.
