ERROR ITMS-9000: "No .app bundles found in the package"]

Hi,

I've been trying to upload my ipa generating Flash Builder using the Application Loader, unsuccessfully, more than a month.

I tried to generate all certificates again and I have not gotten results.

The error is "ERROR ITMS-9000:" No .app bundles found in the package "]" attached image for if you think of anything to anyone. Any help will be very welcome.

I have also tried to unzip the ipa file, access the Payload folder and compress .app inside.

Does anyone have idea what can it be?

If you need anything more than information only have to ask me.

Thanks in advance
