[Crusher stu]

hey guys
Ive Just bought this game from Game.co.uk, as a download
Ive managed to patch the game to the 1.13 what ever it is.
But now When i try and install the latest patch
it comes up with there is no version of men of war on your computer ???
Why is this coming upp ?
Ive tried downloading diff patches and they all come up the same thing ??
Anyknow why ?
Thanks
