nothing sir no error message just crash...after i sign my contract extension then it crash no error message or anything...its my 3rd year already nothing happen but then after i sign my new contract it always crash but if i just play only nothing happen its kinda weird tho maybe they dont want me to sign contract extention in dallas heheh!
i search the net for this problem and found that even in 360 its happen after you sign extention..i guess its really a bug for 2k13 hope some patch will come...and sad to say i will be free agent next summer
