Puttygen key

I am trying to use puttygen to create a ppk file that I can use with putty. I try to import the private key and it gives me the error: Couldn't load private key (ciphers other than DES-EDE3-CBC not supported)

Now I obviously know this is telling me that I have the wrong cipher, but what what do I do to use the correct one? Here ( the instructions that I used to create the keys.

Thanks for the help!

Edit: also, when I open the key this is the top:

-BEGIN RSA PRIVATE KEY-
Proc-Type: 4, ENCRYPTED
DEK-Info: AES-128-CBC

and then some other stuff that I don't think I should share. But the weird thing (to me atleast) is that it lists CBC right at the top there which is what puttygen wants. Why won't it accept it?

Alright, a friend actually helped me work this one out.

Here is a link (
That has the problem and solution in it. Need to use the dev build of puttygen.
