I’ve recently been playing Madden 15 regularly again and when I tried to load up my connected franchise today I was hit with the error above (This file cannot be loaded because it was created with a differente version of the game.). The game hadn’t downloaded any updates that I was aware of, so I was a little panicked. I always keep both an autosave and a manual save of my franchise so I tried loading up the manual save and was hit with the same error. After that I was really panicked. I was mid way through my fourth season and had had an outstanding career so far.
I searched around and couldn’t find any clear solution to the problem. Some posts from 2014 mentioned deleting the latest roster updates, which I did, however this didn’t fix the problem. I also tried completely restarted my Xbox One, but still had the problem.
Ultimately I was able to fix the issue by deleting my Madden 15 save data from the console and downloading it from the cloud again. To do this press start on the Madden 15 icon in your games and apps and select manage game. From there go over to save data and select it to delete it. Make sure you delete the local files only, not both (which will delete your backup!). After I did this I restarted Madden 15 and after it finished syncing the data my save file worked again.
Hopefully this will work for anyone else who has encountered this problem. Thank goodness for the cloud!!
