I've purchased and installed the newest version of Notion 5 yesterday including all of the bundled and expanion sounds. To avoid overloading my C: drive I moved all sounds to a new "Sounds" folder on a separate drive, containing the two folders "Bundled" and "Expansion".
Problem a): Windows crashes almost every time (blue screen!) during process of localizing the sounds after selecting the "Sounds" folder through Preferences -> Audio. However, after rebooting I somehow managed to finally open a score and have all of the expansion and most of the bundled sounds addressed.
Problem b): Oddly enough several bundled instruments are missing (greyed out in score setup), although they are in the correct folder, notified as allready installed when double clicking them (I had to change language from german back to english first, otherwise an error message would occur) and previously having all bundled sounds working properly before moving them to the different drive.
These are the missing sounds: Violas / Violin Solo / Piano / Cembalo / Timpani / human voices (any) / neutral staff.
Searching the FAQs and help forum was of no avail, so any suggestions are highly appreciated!
