Try reposting this information to the spambayes mailing list. I am not a Windows user, so I can't really help you track down the culprit file. Also, looking more closely at your traceback, it seems that ThunderBayes might include its own version of SpamBayes. If so, the above link might not do you much good. Ask the ThunderBayes folks. Skip
