I removed Python 2.7.5 and installed Python 2.7.3. I got exactly the same
error. I have no 64-bit tools installed, even though I run Win8. My users
run a variety of systems from WinXP forward, so at this point I do not use
any 64-bit tools.
I get the error if I run cxneditor.py, click the 'Set Crypto Key' button and
type something in the box. As soon as I hit OK I get the error. I have not
selected any connection files, or done anything other than try to set the
key. I'm usually pretty good at troubleshooting, but on this I am in over
my head.
As a test, I removed the Voidspace install of PyCrypto and used easy_install
to install it instead. I saw some errors during the installation:

Adding pycrypto 2.6 to easy-install.pth file

Without PyCrypto, cxneditor.py does not show the Set Crypto Key button.
With it installed, using that button causes the crash. Could the errors on
the install/compile of PyCrypto be related to this?
I switched back to the Voidspace install, no change. Switched back to
Python 2.7.5, no change, all the error messages are identical. What can I
do to help track this down?

Any ideas?

This is certainly our problem, not yours. I haven't had the chance to move
beyond Python 2.7.3 yet - would you be able to try 2.7.3 instead of 2.7.5
just to see if the newer Python caused the problem?
The other thing that's on my mind is 32-bit versus 64-bit. It shouldn't
error out like you are seeing with either 32-bit or 64-bit, but keys
generated with 32-bit won't work on 64-bit, and vice-versa.
