oil change problem

first time user . i have a zx6r 97 model which has been very reliable. after replacing the oil and oil filter , the oil light stays on and it does not sound like it is picking up oil.i am affraid to run it as i dont want to damage it. i cant seem to get any help where i am and i am now stuck with what to do. the oil light allways went out as soon as it started but now remains on. as far as i was aware after an oil change the oil should pick up within minutes and off you go. but !!!! can someone please help with my problem if possible. thanks. mark.
