Im using windows XP and we have different user accounts for each member of the family. I have found that I can not use limewire on two accounts, once it is installed on one it cannot be used on the other, is this a common problem and is there any way arround this

It can be setup on different accounts. You need administrative privilges to do this.

Instructions are given on how to do this in WindowsXP start>help and support center.

Good luck.
