Game Freeze with 4.0.2

[Dirt12]

Following the install of the new patch 4.0.2 I started the Shinning Fortress Campaign. I transferred to the Furious CA group and accepted an assault mission. Before starting the mission I set waypoints to consolidate all my ships in my sector (Dante?). This required a Q-jump for a few DD groups and also the Hyperion CV group. When I started the mission all started off quite well. All ships Q-jumped successfully into the area and battle commenced on several fronts as my fleets began fleshing out opposing forces. After several kills with few loses I switched to Engineering to power down my Athena’s to conserve power to the Grazers. When I did the whole game froze solid. Was unable to exit the Engineering screen. Although the mouse pointer was still responding I could do anything. I waited about 5 minutes and then attempted ctrl+alt+del to exit the program. No luck so I had to reset my computer. I've attached the errlog.
