 i remember  when i discover the ideas of the question : how will i control the lost of time and credit of player in my pc rental ? at that time i don't have server (its expensive, hard to use and understand) i only write the time of getting in player and set the cellphone timer, i remember the recording ring sound saying "time na, time na.....time na......"heres the story its 4:01am at that time,i did'nt notice when my 3years old boy that siting in my lap, accidentally push the on/off switch of the monitor," i said what happen to the display its gone" i check the pc, the blower is spinning checking other possible cause, to make the story short, he surprisingly push again the on botton and the display appear, i said "there you have it" ,the solution or answer, to my question.  got this idea from my son pterochrist. thanks son
