Thanks, Pat. Excuse me for being slow. I just tried again, deleted the broken assets and reuploaded them. It worked flawlessly this time. FYI, I follwed the first three steps to test (it didn't change my already uploaded broken assets), but ended up with my current setup working, which is: Chrome with a bunch of add-ons Windows 10, Anniversary Update After re-submitting the assets everything is working perfectly now and I'm impressed by your mapping feature. Thanks once more. Kind regards, Phil
