I downloaded this one: Current Milestone: 1.0 · June 13, 2014 · Changelog
The windows self instal one, I also tried downloading the Data patch (which the site said was included in the installer and install that separately) Note that my original game was bought and downloaded from Steam.
Edit: I also just downloaded openxcom_git_master_2015_07_13_1222.zip - built 2015-07-13 10:28 to see if it would fix anything...
