Exciting. Can you make a backup copy of all the files in C:\Documents and
Settings\Jevon\Application Data\tor\, and then delete the cached-routers*
and cached-status/* files and try starting Tor again?

If it works after that, then we really want to see the cached-routers
file that breaks it.

(If you're feeling adventurous, you could put the old versions back into
place and see if it is broken again.)

Thanks!
