CIS : Check for updates bug??!!

I am using the CIS Version 3.12.111745.560 : 18th September, 2009 and CIS is displaying a message that update is available… but when I visit the site all i see the old version i.e, Version 3.12.111745.560 : 18th September, 2009

if i press update…the update begins… what is the version that is getting updated??

is this some kind of a bug or am I missing something ??!! ???
