Some users report that after installing Starry Night Pro Plus from the disk onto OSX the user guide and companion manual are not available when selected from the Help drop down menu. At this time, the issue can be resolved by adding the .pdf files manually. 1. Right click your Pro Plus application and choose Show Package Contents 2. Navigate to Contents --->Resources ---> both Companion.pdf and Manual.pdf should be in here. The files can be downloaded from this article. Just drag them into the folder. if you encounter any difficulty please contact me directly: ksmith@simulationcurriculum.com Kind regards, Keiron
