It might be annoying, but it’s how it is: you payed for the USE of the product, on 1 computer at a time.
You didn’t own the product, when you bought it, so you’re not entitled to decide how you THINK you should be able to use it.
If you want to use the software simultaneously, then buy it 2 times.
But of course, you could just plug over the USB dongle. I don’t see the hassle. Sounds to me like you’re just being lazy or you want to use it 2 times at once, while paying for 1 time.
I might sound harsh, but it’s always something here with some people… Can we stop complaining about what’s fair and not? Please? And just use the software as it is intended?
