How To Set cron job

[admin]

I followed Cronjob setting instructions at viewtopic.php?t=826. But each time i try to import a video from youtube it says video is already processed or in queue. Well, nothing is showing up in the admin section that suggest that any video is in process or in queue. i waited for more thatn 30 mins just to make sure.
Another thing is that when i click on cpanel cronjob icon this is what i get: /usr/bin/crontab permissions are wrong. Please set to 4755.

You need to contact your host, so they can check this.

You need cronjob set before importing videos.
