Serious persisting problem!!!

I'll be as short as can be and explain this situation as best as I can. I posted this problem recently in betatesters section, but I guess I ccan get help better like this. MY Cross IS NOT WORKING. I tried millions and millions of combinations, I even put new copy of windows and still nothing. The tracks and twitching and glitching. sound is horrible. I tried speed, hybrid and tempo- no results. tried various combos with modes- again nothing. I thought of installing older version of Cross, still nothing. The original form the cd, copy of Cross nothing no results. I am soooooo nervous I left my tts now and I am going to some place that I'll be at peace coz truly people I am very stressed. I even thought of making video for you to hear and listen to the sound and everything else by yourself, but I just can work right now. I will go now and if you write something thx in forwards, but I'll be here tomorrow or so coz I just can function right now. I am sorry if I look mad but I am so aggravated and I was a secong from breaking every peace of DJ equipment i own!!!
