[Twisted-Python] Error when trying to import reactor

Thanks for the quick responses! I admit that putting the dlls directly into
the System32 folder was a rookie move, but I desperately wanted to get
twisted up and running :). So now I have a few more questions if you don't
mind answering them. Like I said before, I am a rookie so I am simply
following whatever it tells me to do in the O'Reilly Twisted Network
Programming Essentials book so I downloaded and installed the following:
So do I still have to install openSSL on my machine even though I installed
all of those? Also do I have to use Python 2.5 if I want to use pycrypto and
pyOpenSSL? And finally I was looking around and I didn't see anything that
stated that Vista is even supported. Could that be another problem I might
run into. Thanks again for all the help.
