Be patient, have some faith. There may be some bugs to work out for a while, but this isn't like neurosurgery on your first born child. It's just email.
if you would not press any buttons during the migration process, it will work. give it like 3 or 4 minutes. see if that works. I had the same problem, so my last shot i just left the computer after clicking submit. now it works
maybbe i'll try but nothing worked the mouse wouldnt click on anything even outside the browser ect and when i check the ctrl+alt+delete menu it says not responding
