My Ninja Trader has vanished

[patpat]

Last night when I shut my computer off, I was giving the option of "update and shutdown", which I did. Then this morning when I turned the computer back on, everything was different. My desk top had a different back ground and my Ninja Trader short cut was missing. I found NT under the start button, but when I tried to open it, it said trace file not found, or something to that effect. How can I get NT back? My broker is AMP Futures. I was using NT 7. Thank you.

I have the free version of Ninja Trader. It came with AMP Futures.

Try restore your computer to an earlier date in time when your computer was working normally.
