'deduplicator' question

hi everyone… i installed eMclient tonight, on the advice of someone from another forum… thus far, it seems to work, but i have an issue with the ‘deduplicator’ tool.  from the name of it, it works to remove duplicate e-mails from the various inboxes, which is fine; the problem is that no matter where i tell it to send duplicates to - either ‘trash’ or a ‘deleted items’ folder, it won’t accept either answer.  what am i missing? i think my version number is 6.something, i’m running windows 7 home premium (if you need more info, holler)
