Download older version of Blend

I recently received a Passport SE and updated my PC to 1.2.0.52 only to find that it will not now connect to verify my new phone. There maybe a firewall issue at play here, but interestingly my old Passport was fine a couple of days ago. Is it possible to download the previous build of DekstopSoftware to check this? If so has anyone got a link?
Thanks
John

I need the same thing 1.2 sucks

So it's not just me. Does it appear that they have changed the way that it communicates to the web?
