I completed Section 8 Prejudice installation but when I run the game nothing happens. I uninstalled and re-installed Games for Windows Marketplace application and redistribution but the game still won't run. How can I solve it?
Unfortunately sometimes Game for Windows Live could be a real pain. Try to check if there are any error messages when you launch the game.
The official forum has a list of possible solutions to most frequent problems. Point 8) could be related to your problem and hopefully will help you solve it.
