"The GPO custom templates are stored by Finale in a file named Ensemble.txt. If you want to use the files from Finale 2006 you have to copy the Ensemble.txt from 2006 to the component folder in 2007. Rename the Ensemble.txt in 2007 before copying the Ensemble.txt file from 2006, other wise you will lose any custom templates you created in 2007. Please pass this on to those who might contact you."
