computer crasher

I cannot send any email through outlook. I get the message "The messenging
interface has returned an unknown error. If the problem persists, restart
outlook" or "The operation failed due to a registry or installation problem.
Restart outlook and try again. If the problem persists, please reinstall".
I cannot access email accounts or set them up, change them or add any
accounts because it keeps giving me one of the errors above. I have
uninstalled, reinstalled, repaired will no solution. The only other thing I
could try is a repair install of winXP-pro itself. I have removed my
firewall, AV, and spyware removal with no solution.

P.S. I have not installed SP2 because I run ZA5 Suite and Pest Patrol. Do I
need SP2 to send Email????
