You must be logged in to Steam to play Batman: Arkham Asylum

I am trying to run the Asylum Reborn - HD Texture Pack and when I press the Start Game button on the Advanced Launcher it gives me that message. I have followed the instructions (read them multiple times) and copied the files where they need to go. Why won't it load the game?

I am not sure if I'm selecting the correct files when the TexMod Beta Version 0.9b (c) RS loads up. I select ShippingPC-BmGame.exe as the game. And then select Additional_Textures.tpf as the Package.

I am logged into Steam before anyone asks. I have all the Arkham games on Steam.

I figured it out. Have to run the BmLauncher.exe as admin. Which isn't mentioned in the instructions. I'm going to leave this here as a reference in case anyone needs it.
