Lua crashes on lua_getglobal

So I have this problem.

In my program I have a class (LuaScript) which handles lua scripts for me. However I'm running into a bit of a problem when calling lua functions. I have a C++ function called callFunction which works like this:

void LuaScript::callFunction(const std::string& functionName)
{
     lua_getglobal(state, "update");

     if (lua_pcall(state, 0, 0, 0))
         printf("Error calling lua function: %s\n", lua_tostring(state, -1));
}

But it crashes (which I found out after some debugging) on the lua_getglobal bit but it doesn't crash the first time I call the function (which has me believing that the lua_State* somehow is corrupt) and through even more debugging I get this error message from VS:

Unhandled exception at 0x006CBADA (lua5.1.dll)
Access violation reading location 0xDDDDDDED.

FYI, my lua source looks like this:

function update()
    print("Hello")
end

I have no idea what do to
