Hoping someone can help me?

Hi all, I've only been using this for the last six months until then it was disc's and i am loving using DJ Cross. The only problems i have is i have to re do my play lists everytime i use them? i also have tracks missing or they show as track 3? last but not least if i go from using the auto play to tracks it doesn't always want to do this and i have to close down and reopen??? any ideas and help will be brilliant as i really can't figure it out. Big Thank you
