I bought a new slim XBox last week, did the transfer tool thing online and the console ID matches my new machine.
I noticed some games were showing up as Trials when I was offline. I tried to redownload them by adding them to the queue online and when I log on the XBox, it says "CONTENT ASSIGNED TO ANOTHER CONSOLE"
I tried to redownload one game from the marketplace, I followed the "DOWNLOAD AGAIN" link and it was trying to get me to repurchase it.
This is extremely frustrating, since now a good portion of my purchased content is unusable and the transfer tool says it can't be used until September.
