GDT won't run or validate files

Game Dev Tycoon
#1

Today i loaded up GDT, but refused to move beyond “preparing to launch gamedev tycoon.” I then tried validating the cache but it refused to move beyond 0%.

That might be Steam problem.
Try restarting Steam or reinstalling the game.

EDIT: Okay,maybe don’t reinstall the game yet.

I smell a mod! Reinstall the game please.
