Dear Friends,
I'm using Calibre version 0.8.60 but now i have a problem, since an ERROR appears and details are:Unknown property, element or command: 'sources'

Traceback (most recent call last):
File "site-packages/calibre/gui2/device.py", line 81, in run
File "site-packages/calibre/gui2/device.py", line 332, in _books
File "site-packages/calibre/devices/apple/driver.py", line 3075, in books
File "site-packages/calibre/devices/apple/driver.py", line 2137, in _get_library_books
File "site-packages/appscript/reference.py", line 580, in __getattr__
AttributeError: Unknown property, element or command: 'sources'

Can anybody be so kind to let me know how to solve it? Thank you very much!
