RealTime Physics, 3rd Edition, was released in January 2012. The new edition has updated experiment files. Logger Pro version 3.8.5 has the labs that work with the new version, where as previous version of Logger Pro have the experiment files for the old version of the book.

If you have the 3rd edition of RealTime Physics, and are running a version of Logger Pro before 3.8.5, upgrade to Logger Pro 3.8.5 to get the new files. If you are running Logger Pro 3.8.5 but continue to use an older edition, then you’ll need the older files.

These files are available for download; you may want to remove the 3rd edition files installed with Logger Pro to avoid student confusion.
