For some reason my steam won’t sync and all my settings are gone. My settings for tf2 changed to the one’s I had 1 year ago (resolution, crossair, etc) and cant seem to make it sync the settings again. Steam itself changed it’s settings ( I can’t see the time logs in the chat box anymore, favorite games disappeared from the list, etc).

Anyone know how to solve this? I tried re-syncing it but nothing happened.
