any help any1

First update your Java. Use the JRE offline installer here. Remove your old Java version before you install the new one.
http://java.sun.com/javase/downloads/index_jdk5.jsp

Now delete LW's preferences folder (check in task manager to make sure LW's not running). See point 3 below, or if you've used version 4.10 or older check point 2 as well...you could have a folder in the old location.
Fixes for LimeWire

After that, reinstall LW. Use the offline installer (not the recommended one). No need to uninstall the previous version, it'll happen automatically when the new one's installed.

See if that fixes it

will i keep everything and whats the difference

I guess you mean will you keep all of your downloaded files? Where's your saved folder located? The default is C:\Documents and Settings\your username\Shared. You can check by going tools > options > saving...you'll see the location of your saved folder. As long as your saved folder is in a safe place (like the default) your downloads are safe too.

What's the difference? Difference in what? If you mean what's the difference between online & offline installers...using an offline installer, you download the installer to your computer & save it. Then install from there. Rather than installing over the net. There's less chance of corrupted installation if you use an offline installer.
