application stop unexpectedly

Why did my application stop unexpectedly? I tried everything to solve the error but I can not find the solution. This is a Windows application.

UPDATE:

Are you running NOD32 anti-virus? If so, Google suggests that could be the problem:

You may try to add additional parameterless catch:

catch (Exception e)            
{
    LogError.WriteError("Napaka: " + e.Message);
    LogError.WriteError("StackTrace: " + e.StackTrace);
}
catch
{
    LogError.WriteError("Untyped Exception");
}

In some cases exceptions are not of .net Exception type. Though this issue is specific to CLR 1.1: Throwing Exceptions That Are Not Exceptions

See also discussion at Catch Exception treatment

Additional link: "If the program uses libraries written in other languages, then there may be an exception that is not derived from the class Exception. Such exceptions can be handled by the parameter-less catch statement."
