In reference to the migration thing.....
Try adjusting your screen resolution to greater than 800X600. After doing so I found a continue button at the bottom of my screen and everything worked fine.
Thanks to a heads up by the bros on this board, I was able to save all of my emails by forwarding them to my other hushmail account. When I logged in my browser used the script stored in cache, after forwarding my mail to an alternate account I closed my browser, opened it again and then upgraded upon logging in to my alternate. All of my the mail I sent was there, so now I will just forward them back to my primary account.
Hope this helps.
