You need to upload a crash dump when reporting game crashes. Tutorial here:

Hello,

Please let us know in the note section if you are still able to reproduce this issue on the latest Development build.

If so, please send us a dxdiag report and files from this folder: "C:\Users\<Name>\AppData\Local\DayZ\"

If the *.rar is smaller than 5.000KB, you can attach it here.
In case it's larger than that, please try uploading it to a file sharing website and link it here.

For future reports please refer to the "How to guide" http://feedback.dayzgame.com/how-to-user.html

Thank you.

Hey

Since it has been more than two weeks and you still did not provide us with the files, I am closing this issue.

Next time, please attach the files required :)

Thank You
