Error Message
 

Whenever I load limewire an error message pops up saying:

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

Ive tried uninstalling and reinstalling it and changing some of my options. How can I fix this? Anybody know how to fix this?

Reinstall Java using the offline installer here

Remove your old Java version (add/remove programs) before installing the new version.

Delete your LW preferences folder when LW is closed. Instructions here
Fixes for LimeWire

See if that fixes things!
