Application Loader 2.9 Distribution error

Question

I'm new to the development of iOS. I already have some apps on the app store, and all did this with xcode 4.6.3 and application loader 2.8. Now, I have been struggling to distribute an app to the app store with xcode 5 and application loader 2.9, and every time, whatever I do, I get the same error : ERROR ITMS-9000: "This bundle is invalid. Apps that include an arm64 architecture are required to include both armv7 and armv7s architectures." at SoftwareAssets/SoftwareAsset (MZItmspSoftwareAssetPackage). Does someone know what to do? Please help me out.

Unplugging the iDevice and archiving again did the trick for me.
