AWStats problemer

Jeg har AWStats på en win2003 server som kommer med denne fejl:
C:\wwwRoot\domain.dk\cgi-bin>perl awstats.pl -config=www.domain.dk -update
Create/Update database for config "./awstats.www.domain.dk.conf" by AWStats vers
ion 6.8 (build 1.910)
From data in log file "C:\windows\system32\LogFiles\W3SVC1927339183\ex081030.log
"...
Phase 1 : First bypass old records, searching new record...
Searching new records from beginning of log file...
Error: Your personalized LogFormat does not include all fields required by AWStats (Add %bytesd in your LogFormat string).
Setup ('./awstats.www.domain.dk.conf' file, web server or permissions) may be wrong.
Check config file, permissions and AWStats documentation (in 'docs' directory).
