Failed to submit to the appStore while validation is OK

I try to submit an app to the appStore using xcode 4.3.1.

Validation is ok but when the upload starts I get the following messages:

 

- Apple's web service operation was not successful

- Unable to authenticate the package: 383327395.itsmp

- Exception occurred when creating MZContentProviderUpload for provider. (1004)

 

Does anyone already got this and found a solution?

 

Tx.
