Can not see iTunes library after upgrade to 1.1

I have the same problem dj pro auto updated and now i can see my iTunes.
My iTunes folder is on another drive if that helps.
Not good guys now i have to use my backup mac for tonights gig

some of us have production laptops that will never get upgraded as they work so we don’t want to fix something thats not broken

i wouldn’t of upgraded dj pro if it wasn’t auto updated

I am running Mavericks and NO JOY with iTunes library! Needs to be FIXED!

My iTunes is on an external hardrive, but this has never been an issue until the upgrade to 1.1

10.9.5

i have a very large library and am running Yosemite 10.10.3. i can see all playlists, but any self generated playlist (not genius playlists) starting with the letter “N” or later cannot be opened. iTunes library over 30,000 songs.
