Mar kdid you install with the MSI? We noticed an issue (unreleased fix atm) with problems regarding messagesniffer and clamAV when installed through the MSI. More specifically the files required to run these tools were not included with the MSI version of the application. We will have an update out end of this week which includes a fix to this, if this is your case.
