Please Help! My limewire just stop working suddenly!

[um...help]

i'm been reading some threads on here and i've tried most of the troubleshooting and still the problem persist. anyway, the problem is my limewire just stop working suddenly. i have deinstall it and then reinstalling it again, it and same thing happen. every installation steps were succcessful, but limewire fail to launch when i click on the icon on the desktop or anywhere for that matter. i remove old java runtime environment and install newest one, nothing. my firewalls are all fine and is set to allow limewire connection. i upgraded the adobe flash to 9.0. i have no clue what to do, b/c i tried everything in the forums and nothing could help me. Any thoughts on this...anyone? i have windows xp and tried downloading the lastest limewire 4.12...and no luck.
