Pakaging Error UE version 4-15

I Think Visual Studio Should Be now ok.

I have also tried to export one of the unreal free project you get trough the free vault library.
For this one the packaging works perfectly with no errors. (although It was working before too)

However I have some new issues: This time I have Started from a simple project with just starter content; then I have Import some fbx geomety. Still Packaging process keep failing.
Now I have this kind of error, see file attached.

Before exporting I have also pick the Editor Startup Map and Game Default Map (Maps & Mode project Settings)

Help Please?
