Need help installing the game

Hello! I’m trying to install the client, which I have removed a while ago, but I keep getting error messages, sometimes different every time, like CAS.

This time it is ,ERROR #691269008 (0000000000) File I/O error." and closes the game while trying to load in the world. Any help would be appreciated!
I tried redownloading the files, it is on the right drive, I’m not sure what’s the problem.

Please provide some screenshots and make sure you’re running it somewhere from where you have R/W access.

:fearful:
