Keychain Error

I am having trouble accessing my mobile me mail and also now when I try access MobileMe i.e. Apple menu > System Preferences, MobileMe, I get the following error.

Keychain Error.
There was a problem saving to your keychain. Try again or use Keychain Access to verify your keychain.

Am I correct in saying the Keychain is where all the passwords are stored, therefore is it possible to delete everything in keychains and start again. If possible I would prefer to delete all and start again than to try fix this error.

PLEASE HELP ASAP

Open /Applications/Utilities/Keychain Access. Under the File menu, select "Delete keychain 'Login'" and when prompted select "Delete Reference & Files." Quit Keychain Access. Open Safari. Odds are you will receive an error that the keychain could not be found. At that point, you can choose to create a new keychain, enter your current login password, and you're done.

wow THANK YOU THANK YOU THANK YOU

Its working, is there anything wrong with deleting all keychains on all my macs and starting again

whats the downside of doing this.

Just that the passwords stored would be lost. But if you're ok with that, there's not a thing wrong with it.

I have no problem with that its working like a dream.

I Sync using mobile me and it seems as if the keychains of my other macs have been pulled through again, so I am removing the sync option of the keychains and then going to reset all passwords on all my macs.

Thanks again, im grateful my e mails are back
