ERROR ITMS-9000 when uploading my Flash Pro CC Adobe AIR iPad app to iTunesConnect

I have developed an iPad app using Flash Pro CC. My client has both an Apple iOS Dev license and an Apple iOS Enterprise Dev license. I have successfully packaged and installed the app using the Enterprise license. Now I am attempting to use their iOS Dev license to upload the app to the App store. Every time, I get the same error. Here's the summary at the bottom of the documentation:

1 package(s) were not uploaded because they had problems: 
/var/folders/t1/f88tpcl88xl5f6008k8yjrkh0000gp/T/845653951.itmsp - Error Messages: Apple's web service operation was not successful 
Unable to authenticate the package: 845653951.itmsp 
ERROR ITMS-9000: "Unsupported Architectures. Your executable contains unsupported architectures '[cputype (12) cpusubtype (9)]'." at SoftwareAssets/SoftwareAsset (MZItmspSoftwareAssetPackage) 
Could not start delivery: all transports failed diagnostics

I am not sure what "unsupported architectures '[cputype (12) cpusubtype (9)]'" means or how to fix it. Could this have to do with third party libraries like Caurina Tweener or GreenSock?

I'm on a MacBook Pro 2.9 GHz Intel Core i7 running Mac OS X 10.9.2. I'm attempting to upload using Application Loader Version 2.9.1 (441)

I have updated my OS to the latest version. I have updated Application Loader to the latest version. I have downloaded and installed the latest Apache Flex SDK (4.12.0) and linked it in my Flash Pro CC Compiler preferences. I have downloaded and installed AIR 4.0.0.1628 and AIR Beta 13.0.0.64 and compiled an .ipa using each version of AIR and each one gave me the same error.

I'm reaching the end of my rope here. Any help would be greatly appreciated. Thanks.
