Hi, 
I posted about this issue in this thread:  
https://www.frictionalgames.com/forum/thread-30769.html
It seems that the issue was resolved for a guest and the thread was closed, however my game still will not start.  
I uninstalled my graphics drivers, downloaded the latest drivers from AMD and installed them.  Unfortunately the game has the same problem as before.  
Here is my new hpl.log:
