I had this prob..hastle huh. I fixed it by completely removing all trace of the original limewire installation. Use regedit and search for limewire then delete all references in registry. Search for all instances of limewire using windows search (f3) delete all limewire folders, files and anything that remotely points to or have anything to do with lime wire. Then re-boot and re-install limewire. Dont worry about java..it will tell you if it needs to install it. Good luck
