If you are traveling or otherwise away from a computer and still want to work with the "Wie, bitte?" materials, you can transfer the audio files for the dialogs to your own audio device, PDA, or cell phone. One way to do that is to download the "zipped" file linked here (29MB, .zip). This single file contains all the dialogs for all the Wie, bitte? contexts (chapters).

The mp3 files for the dialogs are also on your CD-ROM. Look in the folder "media", and then in the folder "german_dia_wb". There you'll see a folder for each Kontext ("01", "02", etc.), and in it all the dialog sound files for it. The first few files are single mp3 files, one each for each dialog - look for the word "all" in the file names. An example is "G0107all.mp3": that means Kontext 1, dialog 7. Ignore the ones further down in the list - those are sounds for each separate dialog line.
