I think what people have to do is to extract all the files from the euro.bigs:
Here is the link for the depackbigs .bat program from FIFAX.net:

So what I advise you do is the following:
1. Copy all the "euro#.big and .bh" files from the dlc/dlc_eurodll/dlc folders into somewhere accessible like a new folder in My Documents.
2. Rename all the euro#.big and corresponding .bh files that you've just copied to data0.big/data0.bh data1.big/.bh; etc. (This is very important as the depacking .bat only recognizes bigs named as "data")
3. Copy the files from the depackbigs.rar into that same folder where you've just copied the euro#.big files and run the "exec.bat"
4. You'll see a "-create_paths" folder, and once finished; all the files will be there extracted to their corresponding FIFA12 directories. Copy and paste all the files into the main "Game" folder (not the "dlc/euro_dlc/dlc" one!) and overwrite everything when prompted. (Also make sure that you've extracted the language databases beforehand using DBM12, otherwise the DLC will just have placeholder texts)
5. Remove the euro#.bigs/.bh from their original location in the dlc folder (you don't have to delete them; again you can just make a new folder in dlc/dlc_eurodll/dlc and move them into there). This is to make sure that the DLC picks up on all edited files and not just the default ones.
