Check Engine Code P2A00

so i attempted to program my 2013 370z ecu with hypertech. it started programming it but it never finished. and it keeps saying it couldnt read ecu. called hypertech and they said the unit is not made for 2013 and would only work for up to 2011s and that they havnt come out with a tuner for 2013s. now my engine is making this weird noise when ignition is put to "on" the noise sounds like a fan is on. or like when your laptop is loading a cd. something like that. and to make everything fun the car would not start. any input on this? im thinking hypertech messed up my computer? prolly needs to get reflashed by nissan??
