Can't program selected pids into flashscan

[critter]

I must be doing something stupid, but I have been at this all day and can't figure it out. I want to log with my V1.2 the way I always have using black box mode. But now I can't program the selected pids into the flashscan. This used to work! I have all the latest software, have entered my VIN, OS, PCM type, connected to the car and validated pids. I've read the manual and it looks to be a no brainer but it doesn't work. The FlashScan->Program ... menu selection is grayed out. In fact the only live item on the menu is "Start EFILive Tuning Tool".

Any ideas?
TIA

Edit: I forgot to mention that I CAN program the selected pids into the flashscan IF it is plugged into the car, the ignition is on, and Scan V7.5 is connected. I thought maybe inadequate power on the USB port, but the lights all blink when I plug it in and the software finds the hardware.
