library et history gone after every restart of djuced

hi everyone.
hope to find a solution to my problem here. nearly every time i close djuced and open it again my library is completely gone as are all history files etc. have to reanalyze everytime i start it. its becoming quite unbearable as this affects edited beatgrids etc as well.
most of my music is parked on a nas server however i am 100% sure i have read & writing rights on this server with my computer (imac) and also all djuced files are saved locally on the computer so no reason for the history files etc to disappear. 

any help appreciated.
