Problems since install autocad

Hello,

I have work ok with spambayes 1.0.4 in a Microsoft Outlook plugin at Windows XP SP2 Profesional.

But many days ago, I had install Autocad 2007 and it works fine, but the SpamBayes, when I press the button “Delete as SPAM”; to move the Spam to the SPAM folder, the dialog window of Install Autocad 2007 appears and it ask me for the CD of Autocad. Only happens when I press this button.

 

Can I do?

Thanks
