iCloud has been acting up recently on my Windows 7 computer, it will not sync the photo stream properly.
When I check my %appdata/Apple Computer/Logs file I see the following entries, which most likely indicates the problem:
> [5452 @ Sun Sep 16 21:11:03 2012] [com.apple.console APSDaemon.exe] CertVerifyCertificateChainPolicy failed with error
> 0x80092013
> [5516 @ Sun Sep 16 21:11:03 2012] [YSLog iCloud.exe] defaults key ShouldLog in domain iCloud.exe is (null)
> [5516 @ Sun Sep 16 21:11:03 2012] [YSLog iCloud.exe] defaults key ShouldLog in domain iCloud.exe is (null)
> [5516 @ Sun Sep 16 21:12:34 2012] [com.apple.console iCloud.exe] CertVerifyCertificateChainPolicy failed with error 0x80092013
> [6008 @ Sun Sep 16 21:37:10 2012] [YSLoader AppleMobileDeviceHelper.exe]
I have reinstalled iCloud Control Panel via Apple Updater, however the error persists and my photos do not appear on this computer.
