The directory name and the errors suggest that you simply extracted the 3.1 files over the existing 2.0 ones and that 3.1 was never installed. You need to install 3.1 in a separate directory and then you can run the convertor. The convertor will not actually touch the old installation; it will simply copy over what it can into the 3.1 installation.
