Can open ReShade menu but game and menu freeze

Playing a game called Cataclysm Dark Days Ahead, and I've seen that other people are able to use ReShader on it.
I get Reshader and link it to the exe like it says, get all the appropriate adjustments.
I open the game and click the home button, the menu pops up but both the game and the menu are frozen in place and I'm unable to move my mouse
I've even tried to convert my menu-open key to shift f2.
Any ideas?
