Hi there, welcome to GT Planet. 👍
Thanks for sharing that with us.
If you'd like some help in resolving your issue, we're going to need a little more information though. 💡
What console do you have? 40GB, 60GB, 80GB?
What region are you in? NTSC or PAL? (Let us know where you live if you're not sure, and we'll figure it out.)
Are you using an original GT5

disk? (Don't even think about trying to discuss pirated
copies here.

)
What, if any, error messages are you seeing?
