Keychain access problems.

I was screwing around with Keychain, seeing if I could secure certain programs etc with my trial and error method. Well anyway, somehow I managed to erase all my Keychain passwords and I am now being asked over and over to enter my keychain password for "login." The mail program now also asks for my mail password, which I enter and then click 'remember password in keychain', and then asks for the login password. If I close and re-open mail it asks for the e-mail password again.

How do I get Keychain to stop asking for the login/remember new passwords?

This macbook is my first experience with a mac operating system, so it may be a VERY simple/stupid solution to this problem, but I can't for the life of me figure it out.

Thanks

Sounds like keychain problem, I suggest deleting your keychain file and start from a new file for new passwords.

You mean just wipe Keychain off my HD?
