I am @ my wits end....My Limewire won't launch I have already done all this:
1 - Completely shut down LimeWire, including in the taskbar and system tray
(the system tray is located in the bottom-right corner of the screen,
usually next to the time).

2 - Uninstall all previous installations of LimeWire and Java Runtime
Environment from Add/Remove programs (go to: Start > Settings > Control
Panel > Add/Remove Programs).

3 - Delete all LimeWire icons and installers from your computer (you may
find some on your desktop).

4 - Right-click the Start menu, then select Explore. Using the folder tree
on the left side, navigate to the following directories, and delete them
where found (you can right-click the folder and select Delete):
C:\Documents and Settings\(username)\Application Data\LimeWire (where
username is the name you use to log on to Windows)
C:\Documents and Settings\(username)\Incomplete (this will delete any
partial downloads that were in progress)
C:\Documents and Settings\(username)\.limewire
C:\Program Files\LimeWire
NOTE: If you can't find these folders, go to Tools > Folder Options >
Advanced, then select Show Hidden Files.

5 - Restart your computer.

6 - Visit:

http://www.limewire.com/javabuttond

to re-download and install the JRE (Manual Download > Offline Installation).

then reinstalled Limewire

My thought is that IE is blocking lime wire...
Yes I have gone to IE options and added Limewire to my trusted sights....that didnt work either!!!!!!!!
