I hope the problem is as simple as this...
I can reproduce the problem you are seeing if I connect FlashScan to the vehicle *before* the ignition is switched on.
You should always turn on the ignition first, then connect FlashScan to the vehicle, then to the laptop (if you want to use a laptop).
That is because as soon as FlashScan is powered up it attempts to detect the coms protocol and available modules in the vehicle. If the ignition is off the modules do not respond to FlashScan and so FlashScan does not know what modules are available.
However, once the ignition is switched on, FlashScan should re-analyze the protocols and modules. It is not doing that correctly. I will fix that problem. Meanwhile, try turning on the ignition before connecting (i.e. powering up) FlashScan.
