The smart contract was never hacked, your tokens are safe. Unless you bought during the period their DNS server was hacked you will be fine.
Indeed, there's no coins were lost during the attack and I heard some news and articles that even their coins were frozen or some would say it was gone but after 48 hours they're all set and nothing was changed and developers are already fixed the issue so there's nothing to worry about because Etherdelta is now back into business.
