HELP! D5 file loading stuck at 9% and no recent history versions

Please see the screen shot


Sorry for your situation.
Which version of D5 Render are you using now?
Does this happen in all scenes? Can you open a Demo Scene of D5 or an empty scene? Please have a try.
And, please also try to right click D5, open it ‘Run as administrator’.
Besides, please ​try to turn off ‘Settings-Display-Graphics settings-Hardware-accelerated GPU scheduling​’ if it is on.
