Help needed with certificates

Hi all,

For various reasons I’ve not done any coding for the past few months but have just started to get back into it again.   The problem is that I now have a new iMac running Yosemite and have Xcode 6.1 installed.  When I try to do a build to test on device the Code signing identity field is blank.  There are two provisioning profiles showing (so I’ve obviously done something right), but no certificates (Boo!).  My brain is hurting as iTunesConnect and xCode have both changed considerably since I last used them and I just can’t seem to get my head round it.

Help me [enter name here], you’re my only hope!.

Chris
