Pinfinder problem at Infinity plus combo edition

I’ve bought a new Infinity plus! combo edition box (red color), installed all necessary drivers, and all is working fine except the pinfinder.
When I start Pinfinder application it shows me my virtual COM port, but it cannot detect the Pinfinder and shows error: "too many retries (4)".

What should I do, and also, is there any method to repair it by myself?
