I cannot help, without more information from you.

What version of BYE?
What model of camera?
I presume that you are running a Capture Plan on the Imaging screen, but you did not say. Please confirm.
What is the value of the Save To setting in the Capture Plan Center
Does the BackyardTEMP folder (from the Settings dialog) exist on an always-available local drive (not a removable or network drive) and do you have full access to it?
Does the Download Folder (from the Settings dialog) exist and do you have full access to it?
Have you tried temporarily disabling your anti-virus software? Some A/V software will block image downloads from applications that they do not recognize! If so, you should whitelist BYE as a known safe program.
If your camera has 2 memory card slots and you are saving to both the camera and the PC, please make sure that whatever images you want to download to the PC are being saved to memory card #1.

Please describe, in detail, what steps you execute to reproduce the behavior that you are seeing. Also tell us how BYE reacts.

Thanks!
