This error would seem to be about a missing file at SourceForge.net. When checking for extension updates, I get the following error message, twice. Note that I have gotten this error message in the past with previous versions of OpenOffice.
http://ooop.sourceforge.net/update/extensions.xml does not exist.
Clicked [OK] each time.
The update process went on to find an update for the English Dictionary "dict-en.oxt", which I then downloaded and installed.
I'm running Apache OpenOffice 4.1.1 on Windows 7 Ultimate x64 SP1
