My in-game Power Up Store doesn't work. It says that there's a "script error" in Internet Explorer.

I've tried re-updating the patches. So far it's still the same.

Hmm. I'm using Firefox and it works fine for me. Download Firefox and then make it your main explorer or upgrade Internet Explorer to 8 if you still don't have it.

I have made my default browser Firefox. However the problem still exists.

Here are pictures to show the problem.
