i have a previously owned macbook pro leopard and everytime i try to open only certain applications it tells me the following; " a connection to a network KeyServer is required in order to run this program. Open KeyAccess and log on to a KeyServer"
a previously owned MBP? THE first thing you should do is reformat the hard drive and reinstall the system. anything else is less than prudent and frankly not worth discussing. this will take care of any weird problems you are having with the system now.
