Are you possibly in PERFORMANCE mode instead of EXPORT mode?

I have downloaded the new version of rekordbox on windows 10, I used 3.0 version and it was working, with the new one rekordbox does not see my USB which is definitely connected, I have formatted it on FAT32 but anyway the export button is offline ... what should I do with that ?
