Can't find profile...

I’m new to building for iOS. I followed Peaches step by step tutorial on how to build for a iOS device.
I’m still having problems, Corona SDK can’t find my certificate, it doesn’t even give me an option for my Code Signing Identity. I have the certificates downloaded and my device submitted and everything. [import]uid: 114389 topic_id: 29494 reply_id: 329494[/import]

Now it’s saying my signature is invalid in xCode? Can anyone help? [import]uid: 114389 topic_id: 29494 reply_id: 118407[/import]

There are no a solution as yet, but maybe we can get it solved together.
