Missing files

Windows 10 Engine Prime 1.3.3

Just gone back into EP and I have a load of songs highlighted in red. Normally I would say the original files have been moved but I know they are there. If I go to re-import track information EP deletes all the information it hold and shows a blank entry.

Any ideas ?

If you haven’t do so, try doing a ‘Remove From Collection’ on the red songs then re-add the track back to your collection.
