I recently have had problems with the installation- my limewire would not start at all, i'd double click it, and nothing would happen- i fixed that. Now it works, but it works really slowly. Should i install another java, different from the one that limewire 4.8.1 installs during installation? What should i do?

details----
During my installation problems, i downloaded the latest java from "netbeans" or something like that. It did nothing to help me. So, i deleted it and the java that limewire installed for me, and then reinstalled limewire, including the java it comes with.

questions---
Should i reinstall that java that i had before to enhance performance speed?
