Yes, I guess I should look into projects some time later. Meanwhile, I have managed to lose my "project transformation scenarios" even without updating my version of oXygen XML editor. This is what I did:

1. Choose Window > Show View > Project: the project "simpleLayoutSample.xpr" is displayed.
   
2. Choose Project > Save Project As and save the project as scripto.xpr in a temp folder (just to test this).

Now, when I open one of my ditamaps, I no longer see my project transformation scenarios (Help!). All I see are the default DITA Map scenarios and three global scenarios. Quitting and restarting oXygen didn't help.

Any idea how I can:

• Get my project transformation scenarios back?
• Create a backup of these scenarios so I can safely update my version of oXygen XML editor?

Thanks
