Looks like you got scammed by someone who registered the name bter.
Its a good idea to use the bter interface for depositing. You will get a page telling you to send to btercom or to an address, and to include a certain string of characters as a memo, so that they can identify you.
For BTC deposits its a bit easier. You click the deposit btc link, and it gives you a btc address to deposit to. Send to that address and it will show up in your account after 1-2 bitcoin blocks.
You need to double check that the address they give you is the same one as what you are sending to after doing copy/paste. Someone on this board got scammed a few weeks back because one of their chrome plugins detected bitocin addresses and replaced them with a different address to send to the scammer after a copy/paste onto the clipboard.
I've deposited btc to bter many times and never had a single problem, but you have to be very wary of potential scams that could cause you to send to the wrong address instead of to the exchange address. Bter cant do anything if you fall for these, since they simply never got your coins.
Your only hope at this point is to contact whoever registered the name 'bter' and hope they are a white hat and will return your coins.
