Recover library Rekordbox 5

Hi, I was on Rekordbox 5, now because of the discontinuation, it asked me to convert the library to Rekordbox 7.0. However, after the conversion, I don't see any of my old tracks, the whole library is empty :(

Is there any way to recover my library from Rekordbox 5? I do have some exports somewhere but those are not fully updated. I hope I can recover my original library. I clicked "import library from version 5 and that hasn't worked :(

Thanks a lot in advance for your help!
