All the cookies in my computer were cleaned out by accident. I can sign in, with name and password, but then it never opens up to my mail.

Gmail?

The Google site for gmail has FAQ area and if you search a little the question has probably already been asked by others,the solution is with the question and if you can't open the mail still after that,there is a 'contact us' on the Google site for finding a solution through the site people.

I had problems last night trying to get my mail too,maybe there was too much traffic on the site and it just overloaded.

Not sure.
