The old key was being put in the ~/.ssh/known_hosts directory, where
"~" is the path to your home directory. Where that directory is on
Windows, I wouldn't know, but if you can find it, then you should be
able to just open the known_hosts file, delete the line for the server
in question, and proceed.
Alternatively (and less securely), you can set this in your deploy.rb:
ssh_options[:paranoid] = false
That'll make it ignore host key mismatches. Not recommended, but some
folks just like simple solutions.
