I got several servers, one of them (R6.5.1 on W32) has the german LanguagePack applied (replace mode). Therefore the view "Miscellaneous Events" of log.nsf has the translated name "Verschiedene Ereignisse" and Mailanalysis crashes after trying to access this view with "Object Variable not initialized".
Suggestion: go for the Alias "MiscEvents" of this view!
P.S.: MailAnalyisis is a very useful tool!

Wolfgang
