Hey guys I was about to buy DayZ from steam, so as I opened DayZ on steam to buy it, it asked for my birthday. I wrote 16th May and pressed enter but the problem was I didn't changed the year it remained 2014 and now as I type DayZ on steam to buy it , it says 'sorry you are not permitted to view these materials at this time. PLZ HELP , I want to buy this game!
