Hi folks,

longtime user of Calibre, up until today i have never had any issues, i updated the software to ver 3.6.0 today and now get an error when i try to add a book to the library.

Here is the message:

calibre, version 3.3.0
ERROR: Unhandled exception: <b>IOError</b>:zipimport: can not open file E:\Program Files\Calibre2\app\pylib.zip

Traceback (most recent call last):
File "site-packages\calibre\gui2\actions\add.py", line 424, in add_books

File "site-packages\calibre\utils\filenames.py", line 539, in expanduser
IOError: zipimport: can not open file E:\Program Files\Calibre2\app\pylib.zip

Any help would be greatly appreciated
