I too received the 1.0.2.9000 update.  (Totally different UI etc) The 1.0.01.20 looks like the old 1.0.01.18 with a couple minor minor changes (per release notes) You will lose settings going to the .20 version (at least i did) A cisco support agent said i should roll back to factory settings, and then upgrade to the 1.0.01.20 version. Upgrading version numbers seems to keep settings, but downgrading version numbers does not. Hope this helps ... View more
