The program says it cannot not find SoundLib.
SoundLib is the Sound Library portion of QuickTime 3. Run the QuickTime 3 installer included on the CD, which installs all of the necessary files.

The program says it cannot not find QuickTimeLib.
QuickTime is running low on memory. Turn off all unnecessary extensions and lower the application memory to 900K less than the remaining RAM (which is usually around 5000K). To do this, click on The Digital Frog 2 program icon to select it. Choose "Get Info" from the File menu and change "Preferred Size" to 5000K.

The program runs fine, but the text isn't formatting properly.
The fonts Helvetica or Times may be corrupted or not installed on your computer. Both are required for the proper running of The Digital Frog 2. To fix the problem, simply re-install the fonts from your original system disk.
