having problems with ichat and address book

I was trying to upload an email list of 22,000 into my address book, and it froze up address book. Whenever I click on one of the addresses to delete to try to clear it up, it freezes. And ever since that happened, ichat won't work. I don't know what to do, I have access to address book so I can do some stuff to fix it, I just don't know what. I am a fairly new mac user, so any help would be greatly appreciated.

Why do you have 22,000 e-mail addresses?

Now why would anyone have 22000 email addresses?

Cus hes a spammer?

no i'm not a spammer. its a list of journalists and people to send out press releases to.

Seems to me some kind of mailing list software is a better option than Mail.app

yeah, i figured all that out already. problem is that i already did it and now its not working. how do i fix it?

You can look in /Library/Application Support/Address Book and delete everything there. It should wipe your Address Book.

awesome, it worked! thanks.
