Sorry to hear I would keep your eyes on the forums as the CM KatieFleming may post more contests with more chances to win. Its a bummer that the first key was used before you could use it but keep your eyes on the forums you never know when a new contest might pop up.
Better still, take the plunge and buy a pack you can order the cheapest one for now and upgrade it later should you chose to. Could be the best 40 bucks you ever spend
. this is the right procedure. be sure to select the correct pack (also there is 2 different box where you can insert the code)
I won a pack from cosmic engine and had the same problem. He was able to talk to BE and get me another code. I would ask Polaris to do the same seeing as it was his contest and he distributed the code.
