Current date 19. April 2015, and version Lightworks 12.0.2 / 12.0.3 Beta
Lightworks has a dependancy on older version of OpenSSL v. 1.0.1, which has been superseeded by v.1.0.2
Symptoms are Lightworks quits while trying to authenticate to server.
This can of course be fixed, by downloading older version from bellow, and then either install to system or extract files libssl.so.1.0.0 and libcrypto.so.1.0.0 to /usr/bin/lightworks
