Ineptepub.pyw not working: Error: expected an intended block

[veroniek]

First I downloaded/installed python/pycrypto.

Then I got ineptkey.pyw, ineptepub.pyw(for epub files) ineptpdf.pyw v2 (for pdf files) put all them into my digital editions directory.

Ran ineptkey.pyw. It found the key and saved as "ADEPTKEY.DER " in the same directory where ineptkey.pyw is.

Ran Ineptepub.pyw, an error occured:

There's an error in your program: expected an intended block
Highlighted:
try:
from Crypto.Cipher import AES


What went wrong?
