message in the top of the screen.

HELLO, i installed the reshade but when i enter in fivem a message whith appears me on top of the scrren. 
The message sais that i need to give permissions to a folder or something. It sais me that if i don't do it my preset is not gonna save.
Can you help me pls.

thats fine, it happens to me too, i dont care about it much because i use different shaders everytime i boot up my game. All it does is save the shaders so you dont have to click to enable them next time you join in.
