Emails

I am using Windows Xp operating system I have lost my emails recently and do not know how to get it back system restore will not work because the files have been corrupted how do you fix that you can download something from the web but you have to pay for it surely there is someway of getting back my emails for free. The files can get back bying downloading on the website but it will not let me transfer it to the computer because I will have to pay for it the only way I can get it back is to pay so surely if you can get it back if you have to pay then there is a way of getting it back for free could you advise me it is very important emails that I have lost. How do you find a backup on the computer because maybe it keeps a backup of all the emails.
Many thanks
Peter Gottlieb
