i have a problem with the patch management. If i click on a patch (e.g. Sun Java JRE 1.6.0_31 for Windows (Update) (All Languages)) and click on "update cache" the icon changed to orange but if i refresh the site the icon is grey with a red X and the info "patch failed to cache, check status page for details". On the status page there is only information: Failed to download one or more packages

Please can someone help me, this problem occures with other patches too.
