I recently created a new Login on my computer (running windows xp) for my dad. I tried opening limewire and it seemed to be a little off since it wouldnt open. and gave a message about an AUX Magnet key and that i need to install java

I downloaded version 4.4.4 and when i first tried to install it, it told me i had to remove java software i already had. I did so and restarted and tried again and got the same thing. I removed lime wire and java and started again, so this time i downloaded the java software directly of the website and installing java after installing limewire.
Now im getting the message "Could not open AUX magnet key." and then it tells me i dont have java installed when i clearly do.
I try re-installing java again and it tells me to remove it so i do so and re-install.

i still get the same message and im somewhat frustrated.

How can i fix this.
