I've read the various posts/questions, etc and think I've got it but want to verifiy:

1) Can I download Windows Live Mail to my new Windows 8 computer?

2) If yes, can I get messages from my ATT account which uses Yahoo; my Gmail account and my Comcast account?

3) Before my Windows 7 computer died, I exported both my contacts and messages to a flash drive.  Can I use that flash drive to import those contacts into Windows Live Mail on my Win8 computer?

4) Can I also use that flash drive to import my messages that were on my Win7 Windows Live Mail program?
