tes i click the icon and the computer thinks or 1 second and nothing happens. this happened in my previuse computer and in my sisters and fathers computers aslo. i already tried downlading a new java. uninstalling it what should i do?

Reinstall Java. Use the JRE offline installer here & remove your old version of Java before you install the new one.

Delete LW's preferences folder. See point 3 here (also point 2 if you've used much older versions of LW in the past).
Fixes for LimeWire

Now reinstall LW & make sure to use the offline installer (not the recommended one). No need to uninstall your original LW, it'll do that automatically when the new version's installed

If that doesn't help, try changing compatibility. That's point 5 in the fixes thread.

Also, make sure that LW's on the list of exceptions/allowed list of any antispyware programs, if you're using any.

it didnt work. i deleted all limewire files and unistalled limewire and then i installed offline version but it doesnt open op. when i was installing 5 error messages appeared

Same issue, tried what you said, including the Win 2000 compatability change and nothing, it worked last night and all i did differently was reinstall Battlefield 2142 and that not used to work but now it does and LW doesnt :\ odd
