Please open a command prompt window (press the Windows key and type cmd and then return, that shall open a new window).
Then change the directory with: cd %AppData%/Steinberg/Content
Then type: dir /s
That will do a recursive directory listing.
Click on the icon on the right-top of that window and choose Edit > Select All, and then Edit > Copy.
That copies everything to the clipboard which you then can paste into an email and send to ‘u dot stoermer at steinberg dot de’.
Maybe from the listing I can spot what is missing.
