MT5 Desktop client shuts down after logging in

 
My MT5 Desktop client shuts down as soon as it logs into a demo account.. there's not much time to see the log as it shuts down and I don't know any other way to see the log.. Any help wil be appreciated.
 

C:/users/<you>/AppData/Roaming/MetaQuotes/Terminal/<something weirt>/logs

or, of course, in install folder
