Resolved Minecraft 360 gamesave freezes when loading

Hey, first of all I would like to say I am very new to this, and I apologize if this problem has already been solved.

I downloaded Davyzz's map (the one with the giant Pikachu, Mario Bro's, etc) and made all the ID's identical to mine. When I try to load the map, it freezes my Xbox completely (no sound, no ability to dashboard, completely frozen). I have not been able to access the map at all, and it is therefore completely unchanged. I have looked through multiple threads, spending hours looking through different problems I thought might have relevance to mine. I have tried reformatting my USB and configuring again, then loading everything. I tried moving it onto the hard drive. I have run out of ideas to fix this. Any assistance would be greatly appreciated.

I would also like to point out that I am in no way accusing Davyzz of making a broken map.

Again, thanks for any help!

 

I tried resetting all the blocks to one type, and it still froze. (All dirt if that matters)
