Premiere Pro won't load my plugin

Hello,

I'm developing an importer plugin for Premiere Pro. It works fine if I run Premiere through the Xcode debugger, but when I try and run Premiere Pro from Applicaitons (e.g. stand alone), the plugin doesn't load. When running from Xcode, the"Plugin Loading.log" shows:

Loading /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore/nle_importer.bundle
Loading from disk...
This plugin was recognized by loader ba1058cd-0007-44e4-bf1a-0ef51307b979.

But when running stand-alone, the "Plugin Loading.log" shows:

Loading /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore/nle_importer.bundle
Loading from disk...
No loaders recognized this plugin, so the plugin is set to Ignore.

 I've tried both debug and release builds of the plugin, and neither works. I suspect I might have an incorrect build settings, but I'm not sure what to look for. So how can I make my plugin recognized when running Premeire Pro outside the debugger (stand-alone)?

Thanks,

Chad
