In latest downloads there's a new public property KeepAliveSecs to
enable keepalive packets on the control socket, this should avoid
the connection from being closed on inactivity. 

I've downloaded the lastest v6 beta, but is still doesn't work. I've set the
keepalivesecs to 60. Should I change any other property?

In the server also says that the download has failed, just after finishing
the data connection...

I have a ISA Server 2000, I don't know if that helps...
