They should have been fixed in a patch I thought. I have been hearing the same issues when the game came out, but I thought it was mainly for the 360. Make sure you downloaded the new patch, it also has roster updates (IE. Matt Barnes on the Clippers not on Lakers, etc.)
And you will have to start your MyCareer over, sorry man.
