server uses different tables

i'm having this error in most of the servers and the other parts of the server does not let me downlod the map, it appears to be freezed. basically i cannot play

 

That's just the Source engine being a pain, wait about 2 minutes and it'll work.

 

you need to update your client! go to our downloads page, download Vapor, place it in sourcemods/tf2classic/ and run it. It might take up to or longer than 30 minutes depending on your speed, so make sure your pc stays awake.
