Asking for purchase on generic server

I am trying out the vhusbdarm64 on a debian loaded RPI4 for a SDR server. When I loaded the driver the first few times it popped right up but now it's asking me to purchase the program due to being optimized for the system.
What am I doing wrong?

You must be running the optimized build? Dont do that, run the generic build if you want to have a free trial
