Im sad

I wanted to contribute 0.07 eth but someting went wrong. I ran out of gas?
I'm new to eth, but is 21000 gas not enoug at 21 gwei? Or is it just when there is an ico? and what should I have done better?
21000 Gas Used By Txn: 21000 Gas Price: 0.000000021 Ether (21 Gwei) Actual Tx Cost/Fee: 0.000441 Ether ($0.13) Cumulative Gas Used: 589737
Does this mean i can not join in the game when it starts? If there is a way i still can contribute i would love to hear from thee dev's becouse i believed in you when it was at 500+ eth
