Thank you for your wonderful help! I am trying to find out from Express Coin which address they sent my coins. I think there must be a wallet.dat that wasn't backed up or whatever and I have lost all my money.

This: 35mYvUjMqiAYeobVhLc85PtHCmZKGeZ9Bi is a multi sig address. It currentl has a single unspend output of 0.43610425 BTC. These ~0.4 BTC have been send there on 25th of september. Not sure if that is actually yours.  YES THAT IS MINE

I have one last question. I uploaded a picture of the check I was sending to them (EC) as well as my DL and became an "Advanced Member". Cannot find the uploaded pics now at EC in my account. Should I ask them what happened to this? I want to delete it as it has my bank account number listed on the check and DL info. So scared of identity theft. Boy this is all giving me an ulcer. Wish I had done some research before jumping in.
