Tracks missing upon restart

When opening the software almost all of my tracks are missing. I haven’t changed anything as far as the database is concerned and I am using Engine Dj. Please advise. Thanks!

By missing do you mean the orange triangle? Most likely a drive letter of your external drive changed or maybe you renamed a folder that has your music in it.
Need a bit more info to go on.

Yes the orange triangles, I haven’t renamed anything in my drive though

Check a track in Lexicon (right click → Edit and it shows the location at the top) and compare it to the actual location of the track on your computer

Got it. Thank

This issues has happened again and I cannot remember how to resolve it
