Intermittent startup problems

[NinjaTrader_Bertrand]

Thanks for the report egan857, the System.Data dll was that added in by you? Looks like this would be from a newer target framework than the supported 3.5 one here. What should be then used as reference is the file from the 2.0 framework instead of the 4.0 / 4.5 one. Then please see if this issue would still occur for the setup.

This is very similar to a problem encountered less than two months ago. Then, NT Support said the problem was related to my .NET installation, even though there was no indication that the .NET installation was faulty. I only have trace files dating back to 10/15, but this problem occurred on 10/19, 10/28, 10/29, 10/30, 10/31, 11/1, and 11/4. The problem did not occur on the other dates, and I got a clean startup after the faulty startup on 11/4. So there's no way this problem is caused by a faulty .NET installation, which was "repaired" in September.

Hi, some times NinjaTrader just doesn't start up properly and other times it does. That wouldn't be a really bad problem if it would just display an error message that it didn't start up properly so I'd know to restart the program. Instead, everything looks just fine and then no trades are placed.

There are two problems here: one is that the program isn't starting up properly, and the other is that there's no indication that the program started up improperly. The second problem is more important.

Attached are two trace files, both very small. The first one is from Friday, when the system gave me no indication that there was any problem and didn't place any trades. The other is from today, when it started up with a problem and I noticed it because I looked in the trace file and restarted the program. The second startup worked just fine. Here's a snippet from Friday's trace file (line 115):
