[Where do I go next? [REJUVENATION]]

Where exactly do you go after you teleport back to GDC from Zorrialyn Desert using Claydol? This is in Chapter 13

 

Edit: Nvm I figured it out.

 

[Pokemon Desolation Episode 5.1]

I don't know where exactly to post this but I'm having problems starting the game. When I try to start from game-z, an error message shows up saying "Unable to switch into gameFolder." and nothing happens when I try to open from game.exe. I'd greatly appreciate it if someone can help me out here. Also I'm on windows.
