Halo 3 Master Chief Collection Startup Issue

Hi guys. I was wondering if anyone was having the same issue as me about Halo 3. I bought the master chief halo collection and it turned out to be a code instead of the disc but once I put it in and finished halo 1 and 2 campaign but when I tried to start halo 3 it would come up as if it was loading but wouldn’t load at all. Not even after an hour of letting it sit there to just load any level. Halo 1,2, and 4 work fine but 3 doesn’t load ANY level at all. I would appreciate it if someone could help me out with this.

I’ve heard people having this issue, you posted in the wrong sub forum post in the mcc sub forum or dig through threads in the mcc sub forum which might lead to you’re answer
