tracks wont load

My tracks wont load my macbook rekordbox program. I tried re adding the entire library which seemed to work even though I had 2 copies of every song but it fixed the issue. I turned the computer off overnight and in the morning when opening rekordbox I am having the exact issue. The songs wont load. If I right click and locate them on the finder, I can re add them and that fixes the issue but it leaves me with duplicates of every song. Help! I've already re added my library once and have duplicates of everything. Should I uninstall and reinstall to add the entire library again or should I just re add everything to the current program?
