Hello - since I got the latest DLC something weird has happened to my game. 


Once I've booted if I load it straight away I get the videos at the beginning, the game loads, but then it can't save anything saying it doesn't have the right permissions. If I exit the game and try to reload, I don't get the opening cut scenes and the game crashes to desktop mid-way through the loading screen. 


I've reinstalled it and validated it on steam but that's not fixed it. 


Checked my computer logs and I get the following: 


The machine-default permission settings do not grant Local Activation permission for the COM Server application


Does anyone know how to fix this?
