Limewire Suddenly Quits

Hi, my limewire would suddenly quit from time to time, and since I like to keep my comp on while i sleep to have it ready when I wake up, lime wouldn't be there. It really frustrates me. I've uninstalled it several times and re-installed it, but it wont work. Limewire would just quit. When i exit it out to the taskbar, and leave for an hour or so, the lime symbol is still there, but once i hilight it, it dissapears. Anyone know how to fix it?

i have the same problem and would like to find a solution to this as it is real annoying i think it shuts down after an hour of continous use

dammit ...... i'm not getting enough sleep because of this....
its like taking care of a baby.....

why does it go into the sleep mode after an hour or so of inactivity.....
can somebody help..... please
