Hi! Okay, first things first ... go to blockchain.info and enter the btc address you had the coins sent to. Does the transaction show up there? If you're not comfortable checking this yourself, either Libertas or myself can look into it. I actually have a worsening migraine at the moment and may sign off here in a minute, so you probably want to ask Libertas. He'll see this and you can PM him your btc address (The one you provided to bitinstant) and he can check to see if it's showing on blockchain. If it is showing, then it's an issue on the SR-end of things. If it doesn't show up, then it's a problem on Bitinstant's side.
