Hell NG

I try to update the cache of an office 2010 patch, that is diplayed on the ZCM Patch management. Unfortunatelly I'm not able to run this patch. The status of this patch is red.

MS 2553092 Update for Microsoft Office 2010 (September 13, 2011) (All Languages)FailedFailed to download one or more packages
MS 2553181 Update for Microsoft Office 2010 (November 8, 2011) (All Languages)FailedFailed to download one or more packages


Why it is not possible to download and install these patches?
