I updated to 6.8.0.49 and logos would crash upon launch. I enabled error logging and sent an e-mail to support.
I really needed to get Logos to work, so I formatted my Mac (MBP 15 2015) and laid a fresh version of El Capitan OS X 10.11.2, installed Logos and the SAME issue occurred with no other software or configuration installed.
I am using the Logos 6 installer downloaded from multiple links bearing the same SHA1 hash of 52f19a646c58594aa1c7e0373c5ba364cfcf5349
All downloaded files yield the same hash.
Here is what my LogosError.log shows
