ex-orange,
If you cannot install SP1 for WinXP, your OS might not be legit. If you have WinXP Pro and your CD-Key starts FCKGW... then you were Capt. Hooked.
Take Care,
Richard
P.S. If you would like a program that lets you view your CD-Key, send me a PM with your email addy and I would be happy to email it to you.
