[Snort-users] Unknown ClassType: trojan-activity

I did not notice that the rules were designed for the different versions. Since I am running CentOS 5, I was unable to get the latest to work, but I figured upgrading rules was fine. Is there a way to get a new set of rules for the older versions of snort? Thanks.

Looks like your classification.config file may be missing or out of date.
That being said, am I reading this right that you are running Snort 2.9.1 with a Snort 18.104.22.168 ruleset?

I am upgrading from snort 2.9.0 to 2.9.1, which I figured would be rather trivial. However, I also upgraded to the newest ruleset 2905 to 2940 and I am getting the following error:
WARNING: Can't find any whitelist/blacklist entries. Reputation Preprocessor disabled

ERROR: /etc/snort/rules/blacklist.rules(318) Unknown ClassType: trojan-activity
Fatal Error, Quitting..
Here is the offending entry, but this is the same error for every trojan-activity error.
alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"BLACKLIST User-Agent known malicious User-Agent ErrCode - W32/Fujacks.htm"; flow:established,to_server; content:"User-Agent|3A| ErrCode"; fast_pattern:only; nocase; http_header; metadata:policy balanced-ips drop, policy security-ips drop, service http; reference:url,www.mcafee.com/threat-intelligence/malware/default.aspx?id=141161<http://www.mcafee.com/threat-intelligence/malware/default.aspx?id=141161>; reference:url,www.virustotal.com/latest-report.html?resource=f9dc0803ea4634256eae73b2db61a3c5<http://www.virustotal.com/latest-report.html?resource=f9dc0803ea4634256eae73b2db61a3c5>; classtype:trojan-activity; sid:18247; rev:4;)
Strange thing is that I am using the same entries in my blacklist as before, and those worked fine with trojan-activity. Is there something that has disabled my ability to check for these kinds of attacks? Any help here is appreciated.
