Reply to Traktor saying it can't find my songs, WHY?

When I click to load a song it says warning the track could not be played due to a corrupt or missing file flashing in red. But the file has not been deleted or is not corrupt! This bullcrap happens to me every time I move a song from its folder to another one, meaning after I move it, I have to reinport it to Traktor again! What kind of crap is that? I also just noticed I don't even move my tracks anywhere and it also happens. This is seriously nerve wrecking.
