I seem to be having the same problem. I have uninstalled limewire, updated java, and deleted all the registry keys associated with the program, then rebooted and tried to install again. The program won't even finish loading before it disappears from my task manager. I wasn't having problems with it up until about a week ago, and it happened out of the blue (didn't add or remove any programs or anything).

I have run anti-spyware and antivirus programs and they found nothing, so I can only conclude it has something to do with the program itself, and not my computer.

Any help would be appreciated.
