Unable to Install the OEM Version as it has been shattered into small pieces, seems whilst installing my computer decided to eject the CDrom then close it which caused the disc to jam and shatter!! I don't think microsoft will replace it either as it is OEM and they usually tell you to contact the supplier who provided me with the software, I cant return it to my supplier as they have been bankrupt for over 12 months now. Seems like I'm stuck unless I can get a copy of XP Pro SP 1a OEM from somewhere and then use my geniune key. Thanks for the help anyway, if anyone can help in supplying me with a copy (not a licence key) then please contact me.
