OL 2K -can't send/receive emails, can't compose, can't forward...

[GothGirl]

I have 5 email addresses configured to send/receive mail. Usually I click
send/receive and a dialog box opens that shows me each account as it sends
and receives. As of this morning it stopped sending and receiving. If I
click S/R the dialog box says checking 0 of 0.
If I try to compose a new message I get the following error:
"Cannot create the e-mail message because a location to send and receive
messages could not be found. To add a location, click the Tools menu, click
Services, and then click the Delivery tab"
Unfortunately I don't have a 'Services' option, I have 'Accounts'.

If I go to Tools/Accounts, I see all the accounts still there.
If I try opening a message and forwarding the email I get the following
error:
"The message interface has returned an unknown error. If the problem
persists, restart Outlook."

I've tried re-installing Outlook 2000, I've tried Windows updates, I've
rebooted a number of times, but to no avail...
(and yes, my DSL is definitely up and running. I can access the internet
just fine)
Any help would be GREATLY appreciated.
Thank you,
Sara
