error

HI,

I keep getting this error message (attached) whenever I try to change something in the options. I uninstalled and reinstalled NT7 but still get it...

Hello werido,

Can you please post your latest trace file. You can find trace files at the following location.

Start Menu--> My Documents--> NinjaTrader 7--> Trace--> trace.20100628 for today. (trace.yyyymmdd for any other date)

I suspect it will list a crash as below.

2010-06-28 02:11:30:399 ********* exception trapped *********
2010-06-28 02:11:30:399 The requested operation cannot be performed on a file with a user-mapped section open.

If this is the case, could it be you had a Windows Explorer window opened that contained NinjaTrader files when you were running NinjaTrader?

If not, please check if your virus scanner or any other application locks files in the (My) Documents-->NinjaTrader 7 folder, which NinjaTrader needs to write to. Please make sure to configure your virus scanner so that none of the files in directory above would be locked. Or remove that directory from the scanning list.

yeah, I think you're right that I had that folder open.

Ok, I suggest to close any Windows Explorer windows that contain NinjaTrader files when you run NinjaTrader and check if the crash persists.

If so, please send me your trace file, so I can check what type of crash you experience.

ok, thanks a lot!
