Enough people have complained in aeolus and on the forums about not being able to download the patch that I am compelled to come here and say this again.
You know the message:
The file wasn't sent properly by the server. Try again later.
It is great that you
Fixed a word wrap bug that caused missing characters in tooltips and chat, and allowed certain chat messages to crash the game.
But when that comes at the cost of hundreds of people no longer being able play the game, I would rather you didn't. Your response will be that the people having this issue are using anti-virus software that prevents the client from downloading the files, I know, but I really don't believe that everyone having the issue is using anti-virus. And even if anti-virus is the only issue, do you really want FAF to only be playable by people with no anti-virus software? I'm sure there are people that stop playing or end up not joining faf because of this issue. You have to be able to do better. If you can't fix the updater, and refuse to stop releasing game patches, at the very least you should include instructions for manually installing them on the what's new page.
