I received a newsletter from CNet and under tittle "Hottest Downloads" there was LimeWire, so after so many, many tries from Limewire site, uninstalling and installing again Java, I gave one more chance and
voilá
the soft was installed easy, fast, clean.

LimeWire - Reviews and free downloads at Download.com

No problems what so ever til now.
The music and videos are fast as ever.
