I bought the DLC of this, and now activision took it away. I tried to cownload it again and it wont show up. Anyone else have this problem or have a suggestion as to how to get the DLC i paid for back.

I had the same problem and you just have to completely delete it from your hard drive and then redownload in game and that should fix it.
you cant just redownload it without deleting for some reason.
Hope this helps!

I thought this was just a licensing issue when my 360 died for the 3rd time, but now I can't play the course after getting my original back and erasing and redownloading? Anyone have suggestions? I don't even remember how much the course cost originally..400 ms? or less. any info appreciated. Thanks- Steve

I figured it out. You have to delete the game AND course then redownload and then it works.

Actually that didn't work either. What worked for me next was to delete it, DL it again, transfer it to a memory card, erase it from the HD. Start the game, pull out the memory card, reinsert it, and then it worked again. If you are thinking this game is not worth that much effort you are right.
