iTunes doesn't see my music files after .itl corruption
Hello! It's my first thread here!
I have a rMBP 15" - late 2013 with Mac OS Sierra (didn't update yet to High Sierra since I'm closing a big project), iTunes 12.7.
Yesterday I forced quit from iTunes because it wasn't responding, then turned off the computer.
Today a warning popped out after launching the app saying the .itl file was corrupted and a new one had been created.
The new iTunes library contains all my files & playlists, but every song has the blue "download from cloud" icon (a couple of months ago I have activated iCloud music library).
I still have my "music" folder with all the songs on my Mac, but it seems iTunes doesn't see it.
I tried to open some files in my music folder, and iTunes adds them on the library as they were new songs, they show the icon of "problems uploading to iCloud".
I tried to change itunes media folder, then coming back to the original folder, but did not work.
Any explanation and/or solution (except "download them all again": I have almost 100 GB)?
Thank you for your attention!
