He means, if you leave the Redeem menu up for more than a set amount of time [its rather short] when you go to enter a code it says your session has timed out and you need to navigate back to that page. Which is particularly annoying when you're trying to snag a promo before someone else.
Oooohhh, i get what you're saying now. Yeah, I really hate that too. It happens pretty much everytime I try to redeem a promo code
Thanks for clearing it up man, god it ticks me off, especially if it is a great game like the glyder 2 codes that came out. I saw it right when it refreshed and by the time I had to go back after timing out, all the codes were gone.
