If you are still in escrow, that's good news. If you aren't able to use the resolve button, you should get in touch with SR Support here: http://silkroadvb5piz3r.onion/messages/send_message/104259 Also, if the vendor has disappeared, it is possible either that they are in stealth mode, or that they have been banned. When you visit the vendor's profile, does it show up at all, or does it take you directly to a page for you to send the vendor a message?
