Good Day All Rouvy Members,
For those still experiencing BLACK SCREEN or NO VIDEO issue every time updated to a new version on Windows 10 64 bit machine. Myself have encounter this problem previously and every time have to downgrade to 1.2.2.
Found out the main problem causes this, is the VIDEO CARD. Go to Device Manager, if you have 2 Display Adapters, try to disable one of them. In my case, AMD Radeon is Disable. So far this setting work for me and doesn't effect any other application on my machine. Every new update goes smoothly.
Try this solution. Hope this helps.
