Hey guys, hope Im posting this in the right place- So I bought the LE of Halo 4 and ive used the code for the Specialization unlocks. Being ignorant to the fact the code was suppsed to unlock them early on, I didnt think twice about them. Then I get a message from XBL saying that "Weve noticed you havent used your code for you early unlocks for Halo 4, heres another code to download them". I put in the code and it downloads just fine. I load up the game excited to see what the different Specs are, and I find out they're still locked. I tried to 'download again' from my download history on XBL, to no avail. Im level 43 I believe so I unlock some in 7 levels anyway, but is there something I can do to get my early access Specs or am I just retarded and they unlock at 50 with the others?
