Not sure if you corrected the problem yet or not - I've suffered the same fate at my beloved "best friend" as well with other games. But fear not!! RUN, don't walk to the nearest Best Buy and comb through the bargain bin. For less than $10 of your hard-earned cash (not counting tax of course), you can purchase the game in it's entirety and simply transpose your new copy into your old sleeves or CD holder - or not.
If you live overseas, let me know here on this post (or email below) and I'll
rush straight down to Best Buy and purchase a copy for you and ship it off to you at cost!
Not trying to make a profit, just trying to help out a fellow fan.
