Hello Everyone,
I, too, am having these problems with the patch for update version 1.7.9. I never had any previous updates so my current version is 1.00.631.
I am trying to install World Adventures and the error "Update Error: Invalid File Found" keeps coming up at the tail end of these installation attempts.
I really don't want to install anything thing if it is going to cause problems like some folks here have had...
But, it won't let me install WA without updating the game version.
Is there any way I can bypass this? I really want to play my new game. Thanks for any help.
