This was an interesting read, so I guess I'm the 1 in a million chance guy.
I sent some btc from BTCe to Crypto Rush...
Well the address must of been valid for the btc was sent.. but never received.
Here is a ss of the transfer in the block chain with the BTCe transaction withdrawal.
Also, you can see the the BTCe was has not been redeemed. Just sitting there.
I have conatacted both exchanges.
BTCe cant help, bitcoins have left.

Crypto Rush claims the address was never a Crypto Rush address. (which could be true on the fact they have gone through wallet upgrades and this could of been a false address I copied and pasted)

Note: always copy and paste, and I did for this transaction.
