apk expansion file not downloading from playstore

Question

I am working with the sample apk expansion file downloaded from the SDk. My main expansion file is about 5 MB of size and its format is "main.1.mypackage_name" .

I uploaded my app in play store as a draft application along with the expansion file.But the issue is when the expansion file download progress,one folder is created with the package name under "Android/obb/mypackage". But there is no such file inside that folder.

Sometimes i am getting STATE_FAILED_UNLICENSED message from playstore while the download begins.

What should be the reason of this ? Anything wrong with the file name format or something ? Can anybody help me.

According Goole Play for Developers..

Please note that package names for apk files are unique and permanent, so please choose wisely. Package names cannot be deleted or re-used in the future. Keep in mind that if you've lost your keystore, you'll have to publish the app with a new package name and a new key. You should also update the description of the original app and unpublish it.
