The Dink Network

I've recently installed Dink Smallwood on another computer, but when I select either the main game or a D-Mod it just get an error like this: "The .exe file you selected to launch Dink Smallwood could not be found. Please specify a valid executable in the Options menu."

I don't know what to do I've tried reinstall the game but I get the same error.. Oh, and I'm using windows XP.

I could use some help..

EDIT: It was actually really simple, got it fixed now
