The music library problem is due to one of Windows Vista's new security measures. Windows Vista is not allowing DJ Twist and Burn to make changes to its own music library. To avoid that problem, run the program in administrator mode. Right-click on DJ Twist and Burn"s desktop icon and select "Run as Administrator."
You can also change DJ Twist and Burn"s short cut so that it always runs in administrator mode. Right-click on the shortcut, select Properties and on the Shortcut tab, click on Advanced. Put a check mark next to the Run as Administrator option and click OK to save your change.
Version 1.01 b145 released on 07/07/07 fixes this problem. Download the latest version here: DJ Twist & Burn download
