I purchased the ProFlightSimulator software for about $100.
After installation, I find that it will not work well at all with only a keyboard.

Their website says they offer a "No Questions, Money back guarantee".
I have issued a ticket on their website, asking for a refund.
This was on April 1.
The response was that they are passing this on to their "Refunds Department", April 2.

I added to the ticket April 11, and April 27, saying I had not seen a refund yet.

They have made no response.
