I posted this in another forum, nobody seemed to have an answer, & since it's related to promo codes....here goes: Sometimes when I try to rate a game that I got a code from in this forum a window pops saying null_explanation & it won't allow a review or the ability rate stuff I got free... It's not fair to the devs who gave out these codes to get a rating. It's happened with games like Code Attack, Dynamite Fishing, Keep In Play. wtf? Anybody else experience this?
