I have music maker 2013 installed on my pc, then installed music maker 2018, and non of the soundpools and other instruments could be found on MM2018. I copied the soundpools of MM2013 onto my hard drive. Made a file for soundpools in MM18 directory. Then imported them via the little gear where the option is to add new soundpools. They are all showing in the soundpools tab in MM18. but if I try to open them then it asks for the CD drive to be entered or to reinstall them.
