I'm having almost an identical problem trying to install 2.1.3 the only difference is that I'm running 8.5.1. I'll start up LW 1.6 and it will give me a message saying that there is a new version available, would I like to update? It then gives me an error after I click "yes". So I go to limewire.com and try to dowload it there. After running the installer, there is no change in the program, no change in the preferences, and no new files, all i have is some new stuff in the trash. I've already tried backing up my old version of LW and then removing it from my machine so that the installer would treat it like an instalation of new software, but to no avail. Help please!
