Trying to build LITE versio (Cloned from FULL Version)

So I have FULL version game and I wanted to make LITE version. So I Cloned the project. Made some little changes to game (Only deleted some array data) and then I changed project settings.
In Project Settings I changed App Icons and Keystore details. I also generated new .keystore.

Now I get BUILD FAILED error code:

Saman avaimen sisältävä kohde on jo lisätty. = Same key has already added.

Pufff… what to do? .Keystore file is new and generated just 1 minutes ago. This new .keystore file I already added to right folder and I have set it also in project settings.

Something I dont get it?

If you copied the project you might need to clean out the Intermediate/Android/APK before packaging. Also, check and see if Build/Android/src has files for your old package name.
