I also got robbed hundreds of litecoin for no apparent reasons on BTC-E. Coins withdrawn without any confirmation to my email AND I have 2 factor security too. All theyve given me is my logins and my IP. Maybe we could work together in this case. I feel your pain and your loss
Now CEX.io is a good exchange with excellent security for exchanging LTC and NMC for BTC without charging fees, once in BTC you can easily exchange it for USD with Coinbase. I was happy to see their adoption of being an exchange of LTC for BTC at market rates.
