invalid signature (code or signature have been modified)

Hi, I’m new to corona, I am trying to build an app and run it on the device but I am getting this error. 

I have searched the forums but I haven’t found a solution, I have the latest xcode version 4.6.2, I have valid provisioning profiles on xcode, I use them when I build my iOS apps with no problem.
