i don't know whether i'm having the same probs but it sounds rather similar...
After upgrading my java programme (as prompted), my limewire, which is of the latest version, 4.9.28, won't seem to run properly. The icon is still present in the system tray and i'll see the icon as well in my taskbar but when i click on it, nothing pops up; ie: no screen showing my downloads, etc. Why is this so?
i tried emailing the above paragraph to them under bug reports, but my mail just kept on returning, much to my annoyance... anyway... argh... i'd like my limewire running again.
someone help pls
