like Yanto said in point 3.....
we are no psychics, we need more information then "it doesnt work, how i fix it" when you bring your car to the garage you dont say "it doesnt work, fix it" you tell them the breaks dont work, or the speedometer is not giving the right speed (if you see your speedometer on 200 miles per hour and you get passed by a granny with a walking-aid u can assume the meter is broken)......
so software problems are like car problems, without the actual error messages we cannot do too much
