VW-Tuning-Driver

Hello everyone... I've just downloaded the awesome Model of the VW Scirocco. Because i read that you can simply swap tha cameras with your new tool i thougt to replace the audi TT (Turbo Engine and Manual Gearbox). Now when I try to swap the camera of the Audi with the Camera of the Golf and I want to finish the process by saving, the tool gives the following faliure-note: "unable to save database changes" Why? I don't understand? I tried changing prettymuch every setting. Still the same faliure... Please help me. (I've searchet the site and the inet for 2 hours now...) Thanks a lot in advance for your help EDIT: Sorry... I just figured it out myself. I had to run the application as administrator. Nasty Vista!!!
