I had BitcoinDark at one point. I still have the wallet and private key. I can't seem to find out how to redeem the BTCD for Komodo. It also looks like the entire BTCD blockchain is dead.
the BTCD blockexplorer is no long working. The blockchain should be working, but you might need another peers list. I'll ask in #btcd channel if someone has a good list of active nodes. You can join here: slackinvite.supernet.org
You can swap BTCD on ico.komodoplatform.com (see instructions in OP, you need to also request a KMD payout)
The ico website isn't working, it wont let me register my email. I put my email/pass in, I get a confirmation email, but then when I go to login it says "Email not registered".
Everyone who haven't sent a PM about this issue yet should. I'll send a PM to everyone as soon as the website is fixed.
If we can't get it fixed in time we might have to delay the payout so that everyone is able to swap.
