Itunes 11 backup - not working

Question

Hi everybody
Before updating an ipad app I'm trying to backup data to my macbook using itunes. (this is what the app developer recommends for this particular update)
But the backup is not working and I don't what is happening.
I am running Mountain Lion 10.8.2 and itunes 11 on my macbook.
According to Apple support, I should be able to do this in iTunes 11:
Transfer files from your iPod touch, iPhone, or iPad to your computer
                           Connect your iPod touch, iPhone, or iPad to your computer and select your device.                                                 
                           Click Apps.                       
                           Below File Sharing, from the list on the left, select the app on your device that you want to transfer a file from.                       
                           From the list on the right, select the file you want to transfer, and click “Save to.”                       
                           In the window that appears, select the destination where you want to save the file, and click Open.                       
The file is saved to the selected destination on your computer.
I have followed all these steps, however nothing seems to happen when i click Open.
If I browse to the folder/destination that I had selected when I clicked Open, it is completely empty.
In this case I had created a folder on my desktop to save the backup to.
Can anyone offer me any suggestions?
FWIW I am trying to save .fdb files - which I am unfamiliar with.
Thanks.

Hey guys, I had the same problem. I checked all three options:
1/ Crossfade kept it at 10 as 12 wouldnt work)
2/ Sound enhancer
3/ Sound check
Then I relaunched itunes and it now works. Hopefully it keeps working, and haopefully this helps you guys out also !
