Hi,
Yes it is Handel Gothic BT. Right clicking the file and installing it followed by a reboot should fix the issue.
The issue is fixed for new installs of GameEx and GameEx Arcade Edition but updating to Windows 10 creators edition does break things if a previous install was present.
Sorry that you got an abrupt response. I think we are just a little confused because if you had the font issue you would not even be able to get GameEx started up. If GameEx runs now the font issue is resolved for sure.
