First make sure you have the correct driver for windows 7, then I would look to see what is happening just before the crash at 4500. If the gas injectors are reaching there max 20-23m/sec then it is possible this will cause the system to crash the connection. Up the gas pressure and recalibrate, or increased nozzle size of the injectors may be needed. Make sure you have the correct type of injectors selected etc.
If its connecting at all then you would kinda say the driver is correct, so check the set up.
