File Corruption Solution:
If you inadvertently shut off your system before it saves your alias file may be damaged. Reboot your PS2 and go into the memory card browser. Find the corrupted file and delete said file.

There will be another file on the card which is your "Career" file; don't delete this block. Start up ProStreet and you will be prompted to create another Alias. Once you've done this your career file will load.
