Vista solution on hp comp wired, an hp laptop(wireless), worked for both
ok I had the same problem an everything seemed to not work, until I deleted the newest version of java 6, I searched my comp for all remaining java files an deleted them, I then installed older java thru the link posted 5.0 11,deleted limewire completely thru uninstall an search, then go to limewire an download, limewire basic, when basic installs you will see it install java files n it take a few min to complete, then once it is finished, completely close limewire, making sure icon is not runnin by clock, due to lime default settings, jus cuz ya click x, it doesnt shutdown completley unless u set it under LW settings, an if not sure run task manager, cntrl alt del, make sure it not runnin in the processes tab, right click on LW icon go to properties then compatibility, make sure the box is clicked,,, run this program in compatibility mode for, an select windows xp, service pack 2..select apply then ok, then run lime, it connects fine,,,if u want lime pro then unistall basic thru add/remove dont search for remainin files an install pro, but note thru my trial an error if u install pro first when it installin i noticed it doesnt install java jar files, an will not connect, only by runnin lime basic first did it install the java jar.... not sure y that is but, i reinstalled my pro an works like champ everytime even on comp restarts it turbo connected hope this helps someone peace...i didnt edit the firewall pref in LW I left in default use pnp, alos note my isp is mediacom as well
