No problem! I take it you were able to verify on blockchain.info that Bitinstant has indeed sent the coins to the address you gave them? If so, then it's just a matter of waiting for the transaction to go through on SR's end. As mentioned, if you don't see them in 12 hours or so, send a message to SR Support here: http://silkroadvb5piz3r.onion/help ^^ at the bottom of that page, there is a link to send them a message.
