My Kestrel 4500 (ISS 4.93) and my AB Profile loader (Build 60) are not communicating now but they have in the past. I am running Windows 10 and communicating by Bluetooth. This worked well in the past. I have not changed anything that I know of. The Build 60 screen window says that the Kestrel is connected to the PC but when I activate the Send to Kestrel button, the button blinks once as always but no information is exchanged. I have restarted the PC and the Kestrel, activated the Comport Connect/Disconnect button numerous times but nothing helps. I have communicated this problem to AB on their contact email yesterday but I know they have not had time to respond. I thought someone on the Hide might have solved this problem. The last time I sent an email to AB on their site about a technical problem they did not respond.
