Its deffo something you have done wrong. I have installed the packs on my pc and my girlfriends laptop and both work fine.
Make sure that you open the England Soundpacks Folder and move the sounds folder to the data folder then move the match events folder to the data folder. You have to take them out the England Soundpack folder.
What you need to do is tell me step-by-step on how you installed it and i can help you. If you dont its like trying to teach a bird with no wings howto fly.
Take a screenshot of your data folder using Prnt Scrn button and open paint and then press crtl + v and save the pic as a jpg. upload it to
www.imageshack.us and post the link you get here. That will give me better insight to your troubles.
We will eventually get your problems sorted mate.
