Current Situation. 01/20/2018
The @PirateCaptain hasn't been online since December 4, 2017

The Payday 2 Trainer hasn't been updated for 2 years now and a Recent Update broke the Hook.
You should be able to fix this easily by updating BLT manually, download the newest version here http://paydaymods.com/download/.
