OpenFeint crashing

We are having trouble getting the OpenFeint plugin to work. If anyone knows what the problem might be, or have any suggested solutions, we would like to hear! Thanks.

Our problem is as follows. The Openfeint plugin for iOS is set up following these instructions ( http://support.openfeint.com/dev/exa...os-with-unity/ ), with the one difference being that it is integrated into an existing project rather than a blank project. The file structure and names are also kept the same as in the example instructions. Openfeint version 2.3 was working in the same project without problems, however we removed it while testing another plugin (Prime31 social networking plugin, which now has a new version implemented to the same project). The project when built to xcode will compile and install on the iPhone, but crashes before it exits the loading screen. It gives no feedback, except for it appears suspended on thread 1. We are using Unity 3.4.2, Xcode 4.2, an iPhone 4s, and the plugin version 2.3 which configures the xcode project using a PostprocessBuildPlayer script.
