Hi
Just wanted to air my observations about the above problem widely reported across all versions of MEP, VPX etc.
This happened to me after returning home after several weeks away from my Desktop and I have commented on this in other posts.
The problem appears, as far as I can see and others in other languages have deduced, to be caused by a failed or uncompleted Windows update usually of the graphics drivers. A manual update of said drivers using the Nvidia or AMD installer that downloads with the driver package from the GPU manufacturers website using the Custom> Clean install option often remedies this but in this case it did not.
I was not on the latest VPX patch so tried that but no improvement.
At some point in this I discovered that W10 was down loading the latest 1607 build of the OS (which I had delayed last year but eventually W10 forces the download) so I let it install during which it restarts several times.
Problem solved but why?
Recent advice from FredW on the German forum is to turn off "Fast Start" in W10. Because this puts the system into a Hybrid Sleep state instead of turning it off completely, my guess is that this may not allow the driver or other update to complete as it would with a full Restart. This may explain a comment on another issue I saw by a Microsoft tech recently where he said that a Shut Down is not the same as a Restart, but no explanation as to why.
Only thing I can think is that the hard restarts caused by the OS build update allowed some component of the driver update to properly install, as opposed to just doing the driver update which does not trigger a restart and shutting the machine down only puts the machine into a Hybrid Sleep state if Fast Start is enabled.
A French member who had the problem in my Topic heading posted a solution he had from magix support which I have copied below FYI. This confirms some of my observation are on the right track:-
The driver for your Intel (R) HD Graphics 4600 graphics card is January 6, 2014. Please update by a more recent driver. To do this, use the Intel Update Drivers Utility if possible:
Http://www.intel.com/p/en/US/support/detect?iid=dc_iduu
I could not do that
Also update the NVIDIA GeForce GTX 870M graphics card:

I did this

Your computer has two graphics cards and the system may use the Intel (R) HD dedicated graphics card (built-in motherboard) by default, try to force it to use the Nvidia card by default, I do not know If possible on your computer but try this:
In the Nvidia Control Panel.In 3D Settings -> Manage 3D Settings, there are two possibilities to do either -> Power Management Mode and then select: Maximize Performance or -> Program Settings -> 1. Select a program to Customize: (put magix) -> 2.Select the graphics processor for this program (and there you choose the nvidia card).
I did the 2

Check if the latest update of your MAGIX software has already been installed and if not install it. To do this, use the "Help" menu, "Online update".
Then restore the software defaults.
Start the software (Create a new project) then go to:File> Settings> Restore default program settings.
And now it works as before. I asked why it happened, but no answer. I wish it could work for you too
I am interested to hear others opinion on this.
Cheers
