which seems to affect only those with Nvidia graphics cards, and who updated their graphics drivers "recently".
Ignore the title and read the thread at
Basically the latest official set of Nvidia drivers doesn't seem to work with Maple!!
So if you have an Nvidia graphics card, and you downloaded a new set of drivers in the past month or so (either because you have set the Nvidia driver update to work automatically, or you manually downloaded a new set), then Maple 2016/Maple2015 will no longer work
If this does apply to you, then I recpmmend getting the 'patch' driver set referenced in the second from last entry in this thread. This cured the problem for me. Other solutions are posted in this thread (and they work), but I really can't recommend changing your Maple installation/configuration, just to fix a problem with graphics drivers
