I just upgraded my Limewire to 2.7.11 and encountered the same startup failure. I have tried numerous re-installs with no luck as of yet. I have even e-mailed the company and have not a response as of yet. My older version worked well, but now that I have installed the latest version, I have nothing!!!!! It is interesting that there email states to continually re-install the program if continued startup errors occur....but this does us no good!!!! I sure hope that they get to the bottom of this problem soon so that we can get back on-line!!!!
