After getting the console cable out of the PIX you could well be a little annoyed when you can't SSH in even with the right access-lists. One thing you'll notice is you get dropped out of SSH with:
ssh_exchange_identifcation: Connection closed by remote host

Double check you have the right IP's allowing you to connect:

pix(config)# sh run | grep ssh
ssh 195.195.195.195 255.255.255.255 outside
ssh 192.168.123.0 255.255.255.0 inside

But then most importantly do the following to generate and save your key

ca generate rsa key 1024
