Cannot open Mail after Lion upgrade

[aintree9]

When I click on the Mail icon a message box appears:

Restore Windows
The application "Mail" was forced to quit while trying to restore its windows. Do you want to try to restore its windows again?
The options are: "Don't Restore Windows" or "Restore windows"

Which ever option I select I get the spinning beach ball and nothing happens thereafter.

I desperately need to access emails so has anyone get any suggestions please - I am not very technical so any help would be appreciated.

I have exactly the same problem. Which ever I choose I get "Application no Responding".

I have six years worht of email in there.

Try this: Go into System Preferences, clicked on the new Mail, Contacts and Calendars icon. It should open your POP and IMAP accounts. Make sure that all the check boxes on the Mail account are checked. Restart Mail App. Hope it works.
