I'm using Windows 98 and Limewire 4.0.4. Limewire used to work fine for me but lately I keep getting this error.. Well sometimes I try to open Limewire and nothing happens, but most of the time it opens but soon I get a "Javaw - This program has performed an illegal operation and will be shut down" popup box and it closes. Sometimes it happens a second after I open it, usually it takes a couple of minutes, and it seems to rarely happen while I'm downloading something, but usually it takes forever to start downloading something because Limewire closes before I can even do a search for something. Sometimes it just closes without any error message, and sometimes it keeps closing as soon as I open it but if I restart my computer, it stays open longer. I tried to install the newest version of Java in case that might help but there was some error and it wouldn't install.
