Cannot launch missions

[letterboy1]

I cleared my cache again and I was able to get back in the missions. Go figure. Remember, I was able to play Sunday morning and without changing anything, Sunday evening I started getting that error. I cleared my cache a second time and now I got in several missions and even exited CoD once and went back in successfuly.

For those that have not had to do this before, it is simply this - go to:
C:\Users\"your user name"\Documents\1C SoftClub\il-2 sturmovik cliffs of dover\cache\shaders
Delete all of the contents in the Shaders Folder. Once you play the game again one time, this folder will be rebuilt automatically. It is recommended to do this after a patch . . . and I thought I did it! I hope this works for others with the "Hook" error message.
