iOS Question Installing b4i bridge for second app

Hi

I developed an app with b4i some time ago. So thanks for that! I am trying to develop another one.

I have created development certificate and mobileprovision files but when I run in debug mode I get

=== BUILD TARGET B4iProject OF PROJECT B4iProject WITH CONFIGURATION Release ===

and

The following build commands failed:
Ld Payload/thelifecoachapp.app/thelifecoachapp normal armv7

Is it because I had a previously released version of the app?
