HELP ME PLEASE!

I keep getting the following error message:

"Limewire was unable to write a necessary file because you do not have the necessary permissions. Your preferences may not be maintained the next time you start Limewire, or Limewire may behave in unexpected ways."

Can anyone tell me why I am getting this error or how to get rid of it
please.

Cheers, LJ

Try this version of Java. Use the JRE offline installer & remove your current Java version(s) before installing this one.

If that doesn't help, delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).
Fixes for LimeWire when LW isn't operating as it should
This will kill all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.
