Normal Windows 10 home, nothing special in setup, 8gb ram, 700gb free disk space, running VP with no other apps, quad core AMD A10, Raedon R6 you I think. Runs Lightroom fine, and other exports-to DVD images, not video formsts,-work ok. I'm pretty good with computers, all drivers updated, no driver updating tools, no crapware, no pirated anything, it's clearly the app as others have the issue, two other pcs I can use have the issue, and it's always downloading and redownloading the same file. I just wish I could get hold of a coder/app author to help then I could buy it!
