The subject pretty much says it all. I have been trying to get on to the garry's mod zombie survival server for a few hours and it is still downloading different weapons and maps and whatever else there is to download haha any suggestions on how to speed this up?
I would leave it going over night but I wouldn't want to offend anyone by being afk when it finally finished loading and put me into the game, is there a special way I can talk to the admin and ask forgiveness for this so that I can just try that?

I think you can download zombie survival. Where is says zombie survival in the gamemode options it should have a blue arrow click that and it should download.

download everything that is possible to be downloaded from the internet, this is a glitch happens sometimes where u redownload everything even after u finished it and the load screen is stuck forever till u click cancel.

good luck on solving this
