Yes, he read your first thread. You can activate, and download TU's in the game settings, just like you launch the trainer. Just because you have both Aurora 0.7b and Aurora 0.5b, doesnt mean the settings between them are connected. This is why you must activate the TU in 0.7b also, or it will remove the TU that is in Content/Cache when you launch the game. The TU loader knows this, so it checks the DB to find out if the game has a TU enabled, if it doesnt then the trainer is disabled.
Now you have your spoon fed answer, youtube TitleUpdates Aurora, and you will find 100+ videos on just this topic.
