If you updated this morning to 1.3.6, you may want to download the optional update - I made a mistake in the build process for the installer, so one of the bug fixes for 1.3.6 didn't make it into the build.
The version number will still be 1.3.6, but the build number will now be 2 instead of 1, so you can ignore any warning about reinstalling over the same version.
Sorry for the inconvenience!
