Replays?

So, I ended up playing a game of ship. I was i believe 10-4(very bad for meD:) so in the end i went all out and got a unbelievable for the last 10. Now I wanted to save replay to put on my youtube channel but it said " Replay unavailable please change options" i looked for the tempreplay.tmp in my documents, couldn't find a thing. So yes I am mad but for future instances how do I get replays enabled?
