Hello,
I have a problem, I hope you will help me to resolve it 
When I tried to download the last update of Grim Dawn, in the and of download (maybe 95%), this error happened :
“An error occurred while updating Grim Dawn (disk write error)”
When I tried to launch again, problem repeated …
I tried to unistall and install again, and the same thing happened (always after 95-96%).
Could you give me a solution to solve this problem please ?
Thank you in advance.
