Hi all, I just had a situation where I started up DW4 (latest version), and it had forgotten the vhd files that were loaded, and it would not let me insert new files. I'm running Windows 8.1 on a AMD A6-6400 64bit processor, 8G RAM, 1TB HD. I reinstalled DW4 to cure its amnesia :P Any clues/suggestions? Regards, Bob Devries Dalby, QLD, Australia
