Unable to open or create files, Libre Office crashes immediately

Using Macbook Air, 10.10.3 and every version of LIbreOffice I install, when I try to open an old file or create a new file, LibreOffice crashes consistently. It is unsuable and I am wondering if there is anyone who might have some suggestions how to make it work? Please help!!!

Please explain in detail from you downloaded which file and how you installed LibO.
