I am having the same problem. LW begins to start up whith the black banner that says Limewire5, but then suddenly dissapears. I don't have alcohol on my system. Im using windows xp. I have uninstalled and re-installed both LW and Java, and still no luck. The only thing i can think of is I installed a registry cleaner last week and i havnt run limewire since then and have been cleaning my registry regularly. It's call ErroFix. Could this program be causing my problem with limewire starting and then shutting down a few seconds later? Also, i never get an error message when it shuts down either, it just goes to my desktop as if nothing ever happened.
