could not connect to the server using Auto Discovery

Hi There,

I just purchased the pro version.
I have successfully installed the win application on 2 PC's an XP pro SP3 and a Vista pro sp1 on my home network and signed in successfully into my google account.

I have set up the android pro application on my Sony Ericsson Xperia10 (android release 1.6) and logged in using my goggle account.

I could see both PC's in the connection list, yet when I try and connect to either of them I get "could not connect to server".
I then tried connecting using the RDP that was successful on both PC's.

Help would be great.

Cheers,
