just download mozilla nightly builds at www.mozilla.org (15Mb for win) to fix your docshell.err and copy your k-meleon.exe to bin directory so you can use your kmeleon to open your mail and maybe for download

I guess you get the uninstall problem because no uninstall program comes with the kmeleon setup. Just delete the Kmeleon Directory and the desktop links. Thats it.
