Unblock? Microsoft File Transfer Manager (MSDN)

Does anyone know how to unblock the execution of the Microsoft File Transfer Manager with Avast 5 / Internet suite?
(transferMgr.exe)?

The applicatin runs, but when trying to “connect” to do a transfer, it seems blocked by one of the shields… I just can’t find the right one… in the firewall settings, I have it OK for all connections on this application…
