If you use the upper one (2mb) then dont copy the fifa.db file to ur data\cmn folder
Alternately, you can go to ur fifa directory then data then cmn folder and copy fifa.db to your desktop and extract the files and then at last copy back the fifa.db to the above fifa 2010\data\cmn directory.
If you use the second one (38 kb) you wont loose anything. better use this one

...Just extract all the files
