wget command not working in cronjob

below is my command :

wget -c -O /home/alireza/Desktop/1.mkv http://mysite.com/myfile

and also below is my /etc/crontab documents :

SHELL=/bin/bash

PATH=/sbin:/bin:/usr/sbin:/usr/bin

MAILTO=root
HOME=/
0 2 * * * root wget -c -O /home/alireza/Desktop/1.mkv http://mysite.com/myfile

I intend to run my wget command on 2:00 AM by crontab and also it never ever runs, I do not recognize whats the trouble. the command functions penalty on command line. exists any kind of trouble to run wget command on crontab?

UPDATE:: Im making use of centos 6.4
