I also own this EA and I'm quite impressed with it so far. The results I get from the strategy tester are really good and so far they match the real trades it has done on my life account, including the crashes. The EA uses pending orders so I don't have to worry too much about the latency of my VPS.
My account is in the red at the moment as I started using this EA on turbo setting just before that crash in October. However I should recover soon, and like Rob I survived the other crash about the US unemployment data.
So yeah I'm guessing either the vendor had a lower different risk setting to mine during the US employment data which would have hit the SL, or they manually closed their trades while they were floating in the red.
