Went through this recently! It scared the pants off me.
I think the transfer thing finally came up when I, on a whim, decided to download the new version (saw it was like a decimal off of the version I was using)
After you D/L it and run it there's a button that says "Transfer".
Hit it. You won't regret it.
Oh you have to remember your login at the Solid-Ice site where you D/L keyclone though. Google it if you can't find it.
