I basically got the same issue; when the website was already down my coins have been moved to this address: https://blockchain.info/address/1FFs5hv6JBScJq63aFZvBaNsP6FwnhVgre
Currently they are unspent and probably in the hands of the authorities

The wex support is telling me that they don't possess historical data on transactions and orders of the old platform. So they are not able to approve or deny my words, even though I can provide screenshots of my old BTC-e deposit address.

I’d be alright, if I get 50% of my old balance back.
