This is all the stats I can see for it http://www.megaupload.com/?d=0YTSPKVR There is XP on the game and offline too so it will be in the save, I'll make a new one after 1 more race then compare it...
It never said corrupt when I loaded the save but it started saying "saving" then put me to level 1 (Looks like it overwritten the save)
http://www.megaupload.com/?d=1QNWYQI8 There are two saves, 1st then 2nd with one more race done, XP should have changes but a lot looks changed!!
