I'm not sure if this will help you specifically but it worked for me...

Open steam, library, right click tf2, properties, local game content, validate game catch files.

Hope this helps

So basically, each team will ban a set number of weapons each match, and over a few months valve will collect enough data to nerf or buff certain weapons. There seem to be two main ways of deciding weapon bans: having the host decide, or letting the players vote. Unfortunately, both of these possibilities will most likely lead to arguments among some players. Those who are skilled with and utilize the 'OP' weapons, and those who find them annoying. Just look at the numerous reddit threads on mini sentries - the community is divided by like %50. Players will join up expecting to be able to play jarate sniper, only to troll/rage because their only 'fun' loadout is banned.

TL; DR, until there is a set ban list in place, it'll be just an angry pub.
