The reason why you got the error message is because the crowd sale has ended as the funds raised reached the maximum cap of 465,313 ethers within minutes after the crowd sale commenced.

As @eth commented below, any transactions sent to this contract after the crowd sale has ended will end up with an error, and your funds don't leave your account. You will however have to pay some gas for the cost of this error transaction. This amounts to a few cents, depending on the gas parameter sent with your transaction.

See When can First Blood 1ST tokens be transferred? for the estimated time when 1ST tokens can first be transferred. This date is Dec 23 2016. Trading of 1ST tokens has already been enabled at Yunbi and Gatecoin.

  • You don't need a refund because the error reverts the transaction, meaning that the ether never left your account.
