The program crashed after pressing "Finish" in order to start download

The Crash.txt contains:

HTTrack 3.43.7 closed at '.\Shell.cpp', line 2063
Reason:
assert failed: (end_mirror_msg)[sizeof(end_mirror_msg) - 1] == '\0'


I'm using Vista and it's my fist time I run the program so I'm not sure if the
checked options are right.
