Hi Guys
Same again - I also had the same problem but I just solved mine so I thought I might share here.
Mine turns out to be a spyware program I was running - I installed it some time ago with no problems. After quite a few weeks I rebooted the machine and thats when the trouble started.
Of course I didnt make the connection because it had been quite some time since I installed it.
My suggestion - turn off ALL Antispyware software and try it again. It was blocking the outbound data.
Hope that helps
Regards
