Hello toliss,

Thank you for your post.

Please send me your log and trace files so that I may look into what occurred. You can do this by going to the Control Center-> Help-> Mail to Platform Support. Ensuring 'Log and Trace Files' is checked will include these files. This is checked by default.

Please refer this thread in the body of your email.

I look forward to your response.

Hi

Before you answered I found

http://ninjatrader.com/support/forum/showthread.php?t=102724&highlight=ActiproSoftware

which sounds the same case to me, so I did what suggested there and now I cannot reproduce. Am I a sure however you already noted that something is strange there as this is not a standalone case for e.g here one more

http://ninjatrader.com/support/forum/showthread.php?t=102637&highlight=ActiproSoftware

Anyway thanks for the answer when it comes again I will send to the support, hopefully I will not lose much of my time like this one as it was really hard to catch the exception cause it is not written to the trace all the time.

unfortunately the re installation suggested in related posts did not help, the exception came back after hiding like a virus for some time . I send you my trace

I finally found a solution after a short mail chat with Patrick where he said that Actipro problems are mostly solved with re-installation. Along with the previous posts I realized that even if I re-install NT the problem remain because I kept my old My Documents/NinjaTrader 8 folder. Therefore the solution was first to replace the NinjaTrader.Custom.csproj with a blank empty one from a new installation and if the problem remain apparently I have to blame the serialization settings of some of my templates.

So finally I deleted all custom xml files from the NT directory and haven;t crashed since then! I do not know which setting or template results in such behavior but it is a logical explanation analyzing the data I had.

Hope it helps someone
