Hi Everyone.I just updated to Calibre 2.51.0 and now I am getting this message when I try to import from my computer files.
calibre, version 2.50.0
ERROR: Unhandled exception: <b>ZipImportError</b>:can't find module win32com

Traceback (most recent call last):
File "site-packages\calibre\gui2\actions\add.py", line 234, in add_recursive_multiple

Any ideas how to fix this?
