Hi Panos,

(Apologies didn't have a chance to reply before) - fantastic, that sorted it. 
Thanks for the swift reply.

FFR, a slightly quicker fix than Mike's - perhaps easier to see because this 
was on a clean machine - I looked in keychain and it was obvious that of two 
identically named certs, one was younger than the other; so I deleted the 
older one and that fixed it - no need to re-downlaod.

BTW this has partly arisen because when I used xcode to sort out certificates, 
it seems to be creating ones that expire in a week? Has anyone else seen this?

thanks again,
