Error Message When Trying to Open Game Options

I am using EAH Lite with a dedicated server hosted through Nitrado.

When I try to open the game options I receive the following error message.
I should note that I have just set up EAH today and have never used it before.

Any help would be appreciated.

Hey,

please remove the DiffEnemySpawnRate property from the Gameoptions.yaml. Its not supported by the game and EAH anymore.
