I had the same problem as Trent with some keys not working after upgrading to 18.104.22.168 so I tried to upgrade to 22.214.171.124 but have been unsuccessful. The OS is XP SP3 and the hosts are direct connect and running 126.96.36.199. The download completes, the installation starts, but ends without upgrading. The install window disappears after a fraction of a second and the text in it is garbled. Any help is appreciated.
