Garry's mod server not working

I’m having trouble getting my server to work, I keep on getting this error and don’t know how to fix it

. I have tried updating GMOD and replacing the binaries with the ones Garry Tweeted but I had no luck… Someone please help, Thanks.Also some more info, I used to host it. Thanks again.

The binaries should have fixed it but since it didn’t… I’m not sure… Anyone else know why this is happening?
