For those who are reporting blank screen on startup –

I had the first episode installed from before. I didn’t uninstall it after finishing. Now I downloaded the “episode 2 only”. Then this is what I did -

1. unrar it.
2. go to content, find a folder named “pack”.
3. copy that “pack” folder to your walking dead installation directory.
4. when copying I skipped when it prompted if it should override the “default” subdirectory.
5. then copy and overwrite the three dll files into the installation directory.
6. startup the game with “walkingdead101.exe” from the installation directory.
7. go to “episode status”, you should see episode 2 “installed” now.

I don’t know steps 4 and 5 are necessary, but that’s just what I did, out of wild guess.

Technical info:

C:\Program Files (x86)\The Walking Dead\Pack (Or whatever the install directory is)
Copy the files into above said created folder and start the game with Walking Dead Episode 1.exe.

Note: You Must Complete Episode 1 In Order Too Play Episode 2.
