Okay, I have also been having this problem for over a month at least. Every time Limewire opens, it acts like it's going to work and then, without warning, it just shuts down. One thing I have noticed is that the LW window does not actually close until I either move my mouse, click, or try to type something. I can do any of these things while the program is "still loading" but once it seems to be loaded, doing anything at all closes the program. I have been using Limewire for over a year or more, on this same computer. The problem did not appear to beging from any system or configuration changes, it simply happened one day and has never worked since. Limewire has worked fine with all of the hardware and software currently loaded into the computer. I have also tried the suggestions posted here, including uninstalling and reinstalling both Java and Limewire, at least a couple of times for each. I have also tried uninstalling Limewire both ways, through the Add/Remove Programs section, and from the Limewire portion in the "Start Menu".
