I bought Halo Reach but it says it was and add on and won’t let me play it and I already...

It's an add on for The Master Chief Collection. You would need that game in order to play it.

thanks for replying when the Xbox was bought, it was bought with gta on it already so when I set it up, all i had to do was download the game and I didn’t need the disc. I have been playing on gta5 since December with no worries and now it won’t let me
play.

I have made sure that the console is set to it’s home console and it still won’t work. What do you mean when you say that the license was taken away?

I have followed those instructions and it still won’t let me access the campaign it just says that I haven’t bought it but I’m playing on the disc version so I have?

It won’t let me play the open beta and I bought the expensive one

Just as Smwutches said there is connection here but whenever I try to download somtheing it says "Item not availible from your current location"...

1.But If I bought the game on CD it would install normally?

2.Will I be able to play normal?(No Matchmaking,just Splitscreen Firefight,Co-op...)?

3.Also I bought Halo CE Anniversary and installed normally but since the MP is Halo Reach Anniversary will the MP profile be the same when I install Halo Reach and will Halo Reach install correctly(I don't know maybe it will say item already purschased...)?

(This question may be Off-Topic but it would be great if this was anwsered too)

4.And since I redeemed Halo Reach but I didn't download it,when I will try install it from Disc would it say (Item already purchased or somtheing...)?
