Hello Wyapoint community and 343 
I’ve been having this problem for 4 months now, and I’d like to talk you about it, so someone may help me. Also, forgive me for my bad english, I’m Italian, and Google Translate sucks, so I’m going with what I’ve studied so far
This is my issue:
On Frebruary I’ve bought the Champions Boundle, because I really like Pitfall and Vertigo, and all the cool stuff that came with it
Since that day I’ve been able to use weapons’s skins and stances, but anytime I’ll try and play the two maps the game sais I don’t have the DLC installed.
What could be the issue?
Even when I try to play on a private lobby I can’t access them, and when I get them on MP I have an empty pic where the map picture should be, and as soon as the game start I get sent to the title screen.
I’ve tryed to download it agan, cleared the cache of my 360, redownloaded again after but nothing changed.
Has someone eles got this problem?
Have you solved it?
Thanks for all your help
See you on the battlefield Spartan
Pino, out.
I don’t have an answer for you, but I’ve moved this thread to the “Halo Support” section. It might help your post get seen by the right people.
Hi Pino Show,
Have you checked your hard drive for corrupt files? You’ll know they’re corrupt by the yellow, “!” they have on them.
First: thank you
I’ve checked my Hard Drive, but I have no corrupted files.
Strangely enough I have different versions of saved game, some of them from an unknown profile (maybe from when some friends of mine come to play at my place with theyr profile in an USB) that I’ve now removed.
I’ve also removed all of the maps/modes I’ve previously downloaded, and now I’ll try and download again the Boundle. I’ll let you know what’ll happen 
Again, thanks for your time and support!!!
Thank you so much!!!
So: I’ve checked my HDD after clearing cache and eliminating the saves, and I’ve found a file I’m not even able to find anything about on the internet.
If I were to translate it in english it would be something like “Halo4 game unlocked”, in italian it was “Il gioco Halo4 sbloccato”. Also the Champions Bounde resulted to me as the Bullseye Pack… Anyway, I’ve downloaded it again an it worked this time! Again thank you so much! Gonna try and get some achievements now
Hope to not have any more business with the support section again, but if I have to I know I’ll find someone who’ll help me! Have a nice day!!!
Happy to hear you’re all sorted!
