Sorry for the delay.
429 was never released.
If you are talking about the Yellow car screen, try selecting the Red car and you will drive the yellow car with the key.
This was a bug in the original code which took a long time to 'fix' which I think we never really fixed properly.
SWP was never tested or made to work on Vista/Win7 64 bit so if that is your OS then there are no guarantees what could happen
