If you're encountered a problem in MyCAREER —such as (but not limited to) a corrupted save file, the game freezing during an interview, and attribute resets— we'll be happy to try helping you solve this.
If your issue is either a corrupted or missing MyCAREER file, check out this post about how to re-download the file from cloud.
First off, please fill out a support ticket. Once you have done so, we can set about helping you solve this problem.
Thank you for your patience; we'll hopefully have you back on the court sooner rather than later.
