Historical Mission CTD

[[SJ]Rivet]

I'm getting frequent CTD's when trying to complete the "Past the Rock" Gibraltar mission. I'm wondering if this is specific to the Historical Missions section as a whole, or just the "Past the Rock" mission. I haven't experienced any CTD's (yet) during the Campaign mode, although I haven't got very far into that yet (still patrolling the S western approaches)

My system is as follows:

Mainboard:
Gigabyte Z68X-UD7-B3

Processor:
Intel i72600k @ 4.1GHz

System Memory:
8GB G.Skill Ripjaws F3-12800CL9-DDR3-1600

Graphics Card:
EVGA GTX570 1250MB vram


The mod's I'm running are listed below:

Any ideas on how to cure these CTD's welcomed.
