cant click ok when i receive a quest

Can you provide some more info, to understand the problem?Do you mean that you could you click BEFORE the update, and not later?

Does it happen with all quests?

I encounter the same problem.

After window with the questobjective i can´t press the ok button to close the window.

the game doesn´t react to any key. Even escape isn´t working.

i have to close the game in the task manager.

This happens on any quest

before the last update i was able to press the ok button and continue the game

Try deleting everything in C:\ProgramData\Stardock\Elemental - Fallen Enchantress\screens (it is a temporary folder).

Otherwise reinstall the game.
