Hi Xhaiduk,
thanks for the report, really sorry for the trouble this is making you!
As far as I can tell, there's currently one problem happening to other users,
namely that CN doesn't start up. Your case seems to be different since the crash
happens in the middle of a session, am I correct?
I myself unfortunately haven't been able to reproduce either of the problems, which makes
the debugging harder but still possible.
I'm sure that with a little of your help this can be fixed, so please don't give up on CN just yet

Could you please tell me a few more details:
1) Does the crash happen silently or there's some message displayed?
2) What exactly you have been doing with CN at the time(s) of crash?
3) Can you reproduce the crash, or does it happen randomly?
4) Have you tried running with the "-d" command line switch (valid for 1.8.2+)? If so, is the "log.1.txt" file produced?
(From now on and till with get to the root of the problem, please always run CN with '-d' switch. If you're unsure how to do it, here are the
instructions).
5) Please also try
this version.
