Sims 3 Fast Lane Stuff install error

Hey there

So i've installed and updated all my expansions up until fast lane where im getting a message when i install saying

CRC Error: The file C:\Program files (x86)\Electronic Arts\ The Sims 3\ Fast Lane Stuff\Thumbnails\AllThumbnails.pkg doesnt match the file in the setups .cab file. The medium from which you are running the set up may be corrupted. Please contact your vendor.

I then have the option to abort, retry or ignore... what do I do?

//EDIT

ok i downloaded a separate copy and that has seemed to work thus far 4 more to go!!!

Hello,

Glad to hear you got it to work.
For future reference, remember that you should always use this method:

Open the .rar file you downloaded using only WinRar, which can be downloaded from www.games4theworld.org . (If you use any other software than WinRar, like WinZip or 7-zip, the files will get messed up!)
When
you've opened the file using WinRar, select áll the files in it and
drag & drop them to a folder on your Desktop. When the extraction is
done, close the .rar file and open the folder on your Desktop.
Now,
start by reading the included "# Installation Guide.txt" and you should
be able to get the game to work yourself.

I'll keep this topic open, please let us know the final result! Good luck!
