Oxygen 61 blue keeps freezing fl studio 12

My keyboard (oxygen 61 mk3 blue) keeps freezing fl studio 12.it happens every time i try to pause a project.the whole screen goes grey but the song is still playing; I'll go to task manager to shut the program down and than the sound will freeze for like 10 minutes.I think the problem is the keyboard since it's not connected for couple of days and my DAW is working properly since.Do you guys know what could be the problem?
P.S I use Win 10 64bit
