I think u are using Windows XP SP2. Please disable the IMAPI CD BURNING COM SERVICE to continue with NERO.
Follow these steps :
- on Desktop click Start
- select Control Panel
- click on Administrative Tools
- click on Services
- browse your way down to IMAPI CD BURNING COM SERVICE
- right click (on IMAPI) then select properties
- in the middle of the window, it will say start up type. Click on the arrow to the right and select disabled.
- make sure you click APPLY
I think your problem will be solved. Also this problem was fixed in some previous year issue of Digit. I cant remember the exact month but please check the QnA section there in previos issues.
