link not been working right for ages

rekordbox when opened sometimes does not see my djm2000 driver

i have have to turn mixer off and on and it sees it sometimes

and the link only woks properly when the fire wall is turned off

it was not like this when we go back to early versions of rekordbox

there is northing the matter with my settings all settings are right

rekordbox as all permissions to go through fire wall

i think its down to pioneer way its not working right

please give feedback thanks
