Hi Lars,
I had followed the steps you described already before. As I described I cannot enter the folders in “Documents of Cubasis LE” (only rename them) and when dragging them to the desktop nothing happens.
Only thing I did not test so far (if not anybody else has the same issues) is to de-register my iPad and my iPhone on this PC, uninstall iTunes completely and reinstall it.
But to be honest: My laptop got a new Windows 10 image 2 weeks ago and the latest iTunes version is newly installed. The only thing that I saved from my old image (same Laptop) is the iTunes Folder in “Music” and the Apple Folders in C:\users<my user\AppData[Local and Roaming].
I will let you know the result.
Thanks and best regards,
Karsten
