I forgot to run i2p before Dark Exchange the first time I ran it.
Ha, now that you mention it, I did exactly the same

Now it works, but I can't find anything... I created a offer and searched for it, but it won't find it.
Suggestion: OP, can you add a "in person transfer in " option for trading?
I would like to add an in person option, but that would require some significant changes which I'm not prepared to do yet.
I've added another issue for in person transfers:
https://github.com/macourtney/Dark-Exchange/issues/50I make no promises on when I can get to it. Of course, if anyone implements it for me, I'll be glad to merge it in.
