[syslog-ng] Win syslog-agent PRI

Hi, I have syslog-ng-premium-edition (2.1.8) on an Debian etch and multiple linuxs sending syslog messages to this server, using diferents PRIs. The problem is with the windows agent (2.1.4). In the windows agent I have an message format like this: "<182>$DATE $HOST $EVENT_SOURCE: $MSG", but at the server the received PRI is not 182. At the server I get messages with the correct PRI when the syslog-ng agent is restarted: "Jan 28 10:57:41 10.176.25.108 LogRelay: Application started", with local6 and info, but every message I send through syslog-ng agent arrives at the server with user/notice (PRI 13). Any ideas?
