Hi Eileen, If you run DBT, go to the Help Menu, and down to "About DBT", you will find a De-activate button. Make sure your internet is connected, and all being well the process will be automatic and you will receive confirmation. However, in some cases, aggressive firewalls and such like may prevent the process from going through. In such cases, you should find a plain text file has been added to your desktop containing de-activation details. Save this file And e-mail it to activation@xxxxxxxxxx Another way to de-activate is to remove DBT through Add/Remove Programs. Again if you have internet connectivity, de-activation will be automatic, or again a de-activation text file will be created as above. George.

Hi Folks: A question regarding the deactivation of the software. I need a new hard drive and seem to remember that DBT software needs to be de-activated prior to trying to re-install it. I am not able to locate the place to find out how to deactivate the software. Can some one please advise me? Thanks. Eileen
