No, I didn't know you had to sign into the other Profile. My way of doing it, at least the way that has worked for the past 3 years, I just drag/drop'd the 45410000 folder (which contains the 000003 folder which contains the actual files) onto my Profile folder on my memory unit. The draft classes would still be owned by the original gamertag of whom I got them from and wouldn't be visible in the Memory section of the 360, but in Madden when I select Yes to import draft class they would show up and work. And of course all those years I got draft classes on the PS2 nothing like this was necessary as we didn't have gamertag/profiles with everything locked into it.
Undoubtedly, since my way isn't working this year, they're trying to keep us from sharing draft classes so we'll buy NCAA. I absolutely love college football, it's just that I don't really get into playing it as a video game, that's why I get someone else's draft classes every year. We shouldn't be forced into buying both, they're getting our money for Madden so it's not like we're ripping anyone off.
Well, i'm off to try it again and see what happens. Many thanks to all that helped.
EDIT: Heck yeah, that worked. Just one question though, that's not gonna change any of your settings in your Madden Profile when it loads back up is it?
