Thanks Noel. I'm using BIAB 2015. I got the Everything Pak, it came on it's own usb drive, and because of it's size, I didn't install it on my PC, I just plug it in to use, so I don't have a shortcut on my screen. Perhaps BIAB thinks that it's files are on my c drive and so cannot save, that may be the "access violation". Maybe I should go and install it, but I wonder if other users use BIAB from it's own drive.
