Did you install the driver? Did you follow the installation instructions? If you think you did install the driver, check in Device Manager whether Windows is using the correct one. If you plugged the device in before loading the driver, Windows most likely will have chosen a standard driver rather than find the correct one.
If you have loaded the driver after you plugged in the device, try unplugging it and use a different USB port. If you're lucky, Windows will then use the correct driver.
I hope this doesn't hurt, but in case you don't know and for anybody else considering a simulator, you don't need to buy anything expensive. The 22 in 1 Simulator cable that you can buy from Amazon for $10 comes with a cable, a USB adaptor and Phoenix 5.5. All you need is a trainer port on your transmitter.
