Help with a gmod module

[b]Note, this is to essentially expose Steam Chat to lua using Steamworks[/b]
(yes i know there's pretty much no reason for it, butwhatever, this is just for shiggles)

I'm attempting to add a hook to gmod to run whenever the local player receives a chat message over steam. Normally I don't like using Visual Studio, but that's the only way you can use Steamworks on Windows. It uses Visual Studio 2013 Express

Here is my current project file: [url=https://www.dropbox.com/s/ye12l97x298mev5/SteamChatBinding.zip]SteamChatBinding[/url] I apologize in advance if the code is a bit messy or disorganized. I was more or less making this up as I went along.

I've determined where it's causing the game to crash. Line 27 in main.cpp:

steamFriends->SetListenForFriendsMessages(true); 

I assume this is a problem with how gmod handles Steamworks? The dump file gmod produces gives me the error:

The thread tried to read from or write to a virtual address for which it does not have the appropriate access.

That's about all I got.

However, while we're at it, I'd like to ask a few more questions about this kind of stuff. If you look around my comments in main.cpp, I half-assume that gmod is running SteamAPI_RunCallbacks() and SteamAPI_Init() internally. Is this true? (I have no idea why it wouldn't, but I've seen more bizarre things.)

Thanks in advance for your help.
