sorry - i don't have access to the developer-forum (maybe someone will give it to me ;-) the installer has a little flaw. he deletes the /root dir. the problem is, that awstats stores it's script awstats.php (run every night at 4.00 with cron). so if you install the update the update-script will delete this file and awstats will not work any longer. after copying the "old" .php file everything works fine.
