Package undefined

Hi,

I have created a PDFAU5 package and built it sucecssfully. The pdf reports were generated with sucecss code and the log files contains no errors. But when I try to deploy the package, I am getting error message that package is not ready for deployment and is undefined.

Here is one screen shot given below. Can you please advise what should I do in this case, should I built the package again or is there anything missing when the package is coming as undefined. Also there is nothing coming under the enterprise server as you can see the screen shot that it is blank. I really appreciate your time and co-operation.
