Just a shot in the dark, but make sure you have AtUsbHid.dll in your “LR” subdirectory. I remember seeing this problem before, but my senior memory is foggy hee hee. I have LRDemo, LRTimelog and LRlog all running fine on multiple computer with Win 7 Pro 64. Just checked my laptop and that .dll file is only located in the “LR” subdirectory.
Hope that helps.
Also if you still have the problem fire off email to Richard at Porcupine Electronics. He’s normally very responsive. [email protected]
