I installed update #453 64 bit for Vegas Pro 13 on a desktop running Windows 8.1 Home yesterday. Vegas Pro 13 now doesn't show anything in Windows Explorer. I rebooted a few times and still have the same problem. I've dragged files from Explorer from outside of Vegas to the timeline and that works. Has anyone else had the problem? Can anyone suggest a solution? (I still also have Vegas Pro 13 on the same desktop. No problem with Explorer there.)
