I'm having a few issues, initially I was having issues with getting the DX11 and High res packs to enable at all.

They would patch but in game it was still greyed out in the menu. I tried to reinstall the game, went through and deleted any traces of the game I could find to do a clean install. Now when I tried to patch to 1.9 it says that I am already on that version but I am not. Same thing with the DX11/High res patches.

Now when I go to start the game I get "Failed to initialized the GameStartup Interface!"
Here is what my game log file says:
