There is new patch available. It fixes an issue primarily with low end machines that were unable to deselect detailed terrain. It also fixes a potential issue with skins downloading.
If you already have 2.14 you can also manually download the patch from here:

If you are running Vista or Windows 7 and can't get the patch to install, you will want to download the patch and then right click on it and select "Run as administrator". If you want to use the autoupdater, run AH as an administrator prior to going online to use the autoupdater.
