lost an entry to the party million (640$)

[voltron.]

In december I won a 33$ satellite into the monthly party million guaranteed. I couldn't play in december since I was travelling, so I did what some 2p2ers said to do and unregistered. bingo, I have a freeroll entry to the party million in my account. I was going to use it in January but got stuck in traffic and couldn't play that specific day. A week later I check to enter the Feb one and it isnt there anymore. Party told me that you can't do the unregister thing and if you win a satellite you have to use it that month, but still WTF.
