Steam validation rejected TF2

[Miners]

Using Undead patcher, I downloaded TF2. After installing I tried to enter a server, I got a message saying Steam validation rejected. Any help? I hope this isn't a stupid question...

Sorry but...

...you just can't play on cracked servers. VALVe's Anti Cheat System prevents - as far as I know - the games downloaded with a cracked client from playing online. It's a technical problem the crackmakers didn't manage to solve.

Here's a list of cracked servers that should work
Team Fortress 2 servers How to join : Copy an IP address and go to TF2(enable the console first), and once in the console, type "connect >IP here<"
