error signing identity "-"

I had to rebuild my iMac a few months ago and I restored from my Time Machine backup.

I now need to make a change to an app but what used to compile without error is now failing at the codesign step with:

Signing Identity: "-"


As far as I can see, all of the account profiles are valid with expiry dates in the future. The only 'odd' thing is that some have a 'Download' button in the 'Action' column of the 'Provisioning Profiles' seciotn of the account details - when I select the "Download All Profiles" button, they turn grey but never seem to download or disappear (even after aiting for several hours!). Looking at the 'developer' web page, all of my certificates and provisioning profiles are all active.


Any ideas welcomed


Thanks

Susan
