I have been using limewire for many years now and suddenly it stopped working. It would try to open and then would stop. I uninstalled it and dowloaded limewire pro but I am still having problems. LImewire acts like it is going to open but then never does. Pease someone help me. I have windows xp and using norton. I have tried to disable thing is norton but still no luck.

What version of Java are you using? Try this version. Use the JRE offline installer & remove your current Java version before you install this one.

Now reinstall LW (if you reinstall Pro it will automatically use the offline installer. If you reinstall a basic version, make sure to use the offline installer).

If that doesn't help, delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).
Fixes for LimeWire
This will kill all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.

Or try the other fixes in that thread (change compatibility, run as administrator).

Thanks for your help! It worked!!
