Definitely downloaded it.
Its got something to do with being logged into Xbox Live.
If I login to Xbox and my Xbox Live profile - I don't have any problems when I load Disney Infinity.
However, if my son Logs into his profile first (which doesn't have Xbox Live) - thats when we see the problem.
*BUT* if we login under my profile, with Xbox Live, and then Start Infinity and get all the way to the main menu - then Sign my profile out, and his non-Xbox Live profile in -- we don't have any problems.
Something is definitely screwy on how Disney is verifying the download. Its somehow using Xbox live as part of the verification process, instead of simply checking the local machine (if that makes sense)
