Sims 3 World Adventures Error:The volume for a file has been externally altered so file is no longer valid

I've torrented lots of games before and majority of my Sims 3 and 4 games.

I had all of the expansion packs besides World Adventures and all the stuff packs so I downloaded your The Sims 3 Complete Collection. All the stuff packs downloaded perfectly, no problems at all until I got all the way down to the list to WorldAdventures. I read the Installation Guide and read about changing the SKU value in Regedit to 2. So I went into the program, found it easy and changed mine from a 7 to a 2. Started to install the game, serial code worked fine then at the beginning of the installation an error message came up that said,


file:E\TheSims3WorldAdventures\Caches\China.objectcache
Error: The volume for a file has been externally altered so that the opened file is no longer valid.

I read over some forums in your website and I tried changing the SKU value to 1, I saw China in the error code so I tried changing my file to China, CN, in the regedit, still didnt work. Is there something wrong with the file or is there something I'm doing wrong.
