Awstats acting weird

does the following happen to anybody else: Everytime I go check my stats on awstats it works fine but lets say I dont check it for one day then all the stats are 0 for that day… its as if the server was down which is not the case… Why doesnt awstats update itself automatically… i have to update it myself… otherwise its 0…

Do you have a cron job set up to run the update once a day?
