Live Update Error

My Live Update runs weekly and today it gave an "Update error" message.  Same when I rechecked it manually.

 

I see that others seem to be having the same issue.  So I checked the version and it is 10.1.2.  My Mac Is OS X version 10.5.8

 

I did open the Update page listed in below -- but no "button" opened to click on.

 

Please help.  Thanks
