You MUST register the ethereum address that your EOS is sitting in if you want to receive your EosDAC.
Here is a youtube video detailing how this can be done on a Ledger Nano S using MyEtherWallet.com.

Register now to get the most from your coins.
Here is a written step by step instruction guide that is so perfect I couldn't make a better one so I won't try.
