Cannot launch missions

[letterboy1]

I started getting the exact same error message just yesterday. I started up CoD in the morning for the first time since the official patch and flew several missions. When I got back home in the evening I started up CoD and every mission I tried to start gave me that error. I could get in the the Custom part where you choose which plane you want, but when I clicked on "Fly" it gave me "Hook: {_Gun00} not found." Weird! Like I said, it worked just yesterday morning.
