Build fail after App ID change

[MIke_E_1]

I have made a Game App with IntelXDK/cocos2 tryed to uppload it to Google Play and got the following error.

You need to use another App ID because the App ID is taken, or actually in Swedish it says packet name is taken, but i guess its a translation isue.

the current app id is ( xdk.intel.cocos2d.js.landscape.project ) Build woks just fine. But i need to change that so i can uppload it to Google Play. So i did go to Build Settings and changed the App ID. And now i get the folowing error message when i try to to build.

An error occured while building the application. Verify you build assets are correct and try again.

The only thing i did change it the App ID

Also tryed to restart the project, made a coppy of the project and removed the zdke and xdk files an imported HTML5 code base. Changed the App ID but that dident work.

Would be realy happy if some one cud explain why i can't change my App ID.

I did find the problem. There where rules for app id

tree parts separated by a ' . ' and no part shud start with a number.

example abc103.cde.v01 works

Not working 
103abc.cde.v01
103abccdev01
