You can try this version or one of them LimeWire cvs builds (4.13.4jum489)
No installation necessary, just drag & drop the program to desired location after dmg opens.
*Note: Jum has not updated this CVS version is over a month, so it's not as update as it normally is. He must be on holiday.

You may want to try deleting your LW preferences folder whilst LW is CLOSED; it is found here:
/Users/your_username/Library/Preferences/LimeWire
