You're welcome.
The only difference is, that the offical plugin has been developed by scirra, and the PhoneGap AdMob Plugin from cranberrygame. Both are using the same admob plugin at Intel XDK and as far as I know cranberry did work together with scirra to make the AdMob plugin.
I'm not sure why it has stopped working. Maybe it's caused by the latest Intel XDK update or the path is just wrong. But to get clarity we need to wait for cranberrygame's respone.
If you want to compile your game just remove the admob and/or the Game (located in the intelxdk.config.additionals.xml) plugin from Intel XDK's Third Plugin area. You just can add them later again, when all starts working again.
