QCAR AR no working with gui menus

Hi Everyone,

I'm very confused right now; I've been working on an AR game, and i had it just the way i wanted it.

So this weekend I added extra scenes to the game for all the menus, and was very pleased to have them all working.

However now my AR game scene is no longer working properly, the background is just black, Its not showing the camera view, and its not tracking anything.

Ive even disabled all the other scenes in the build, but it just refuses to work now. Can you think of any reason for this?

I'm using a Samsung Galaxy S2 with the latest Vuforia (downloaded last week).

Any help or experiences would be really appreciated!

Thanks, - Graeme
