First problem: i cant load my car on slot 4 (63 Impala). It get stuck at customizing car.

second problem: when i load my other cars, I lost all upgrades i done over the years. Everything is back to default
and nothing is available anyone. Any Help?

I also went to my cars page and i see ERROR2302 by The Shop next to all my pumps.
i never seen that before..

Any help would be appreciated!!!!

Looks like you haven't used the game since the last version update. I fixed your car in slot 4, but you will need to rebuy your upgrades due to the updated version.

Thanks for recovering my Impala. I care about that more than the upgrades lol
DaddyLacCoupe80, told me what happened. So i been doing my upgrades again.
