Hi GJO
It would appear that your latest Windows update has caused your current problem.
Although you are running Windows 10 Home Edition there will be a version number.
The 3 most recent Windows 10 versions IIRC are 1607, Anniversary. Creator 1703.
Go to Start icon
Settings icon
Select System
Select About
This will show the version you are using.

There are number of things that you can try.
Make sure that you are running all applications as administrators.
You need to run Windows 10 in a compatibility mode usually Windows 7.
Another option is to make a change to your SH3.exe in properties by ticking the box 'Override High DPI scaling.'

You also need to check your driver version.
If your GPU is a Nvidia then open the Nvidia Control Panel\Help\System Information and you will see your driver version.


Windows 10 Creator version 1703 was recently updated by Microsoft to version 382.05 which is incompatible with Silent Hunter.
If you have this version then check out my tutorial at the top where you will find useful information and fixes.
