PRO STREET PS3 ERROR!

[Gaspar dursh]

I was doing a carrer in my ps3. When it was 31%, i bought a R35 and I was tuning it when the game stopped to work. I thought it was normal, so I entered in a Race Day, and after races the game stopped to work. This problem is just in Carrer, outside it Prostreet works very well. I thought the problem was GTR, but when I click to sell it, the problem returns. What can I do? Is GTR the problem?
