The error "Unable to connect to the world. Please check your connection to the internet and try again." appears everytime I attempt to load the purchased game Mars Protocol.

• I have no problems with my internet connection or settings with the Xbox.
• I am able to load every other Minecraft saved game with no issues on the first attempt, only Mars Protocol is experiencing this load problem.
• Repeated attempts to load this game i.e. 20-40 attempts has been working to eventually load the game. However for the past two days this repeated process of loading attempts has not been successful.

I am enjoying this Mars Protocol game very much and the inability  to load is aggravating. Please remedy this glitch asap. Thank you
