Question: I signed up for Social Club, linked my Gamertag/PSN ID to the account, but I can't seem to get any of the Social Club challenges to start.  What could be wrong?

Answer: The most common reasons for Social Club challenges not starting are:

• Not realizing you have to go to the the location where the challenge is to start it
• Not being connected to the Internet or signed in at the time
• Having cheats on in the game, which not only disables trophies/achievements but also Social Club challenges
