and what if I lost this confirmation email ?

It seems that I have to click on an activation link in the purchase confirmation email... But what if I don't have this purchase confirmation email any more?

I went into the same problem as you describe, Jason Gress.

I finally found my mistake: do not drop the tree in the tabs outliner window unless you see the blue marks indicating that the target window has "understood" what you are going to drop there.

If you don't see the blue lines marks, the content will be handled by the default browser behavior which is: display it.

If you see blue lines, this is the Tabs Outliner code which will handle your data.
