Connection problems?!?

[maxigt]

HELP! Whenever I try to join a server, I says "You cannot connect to a server which is operating under a different protocol version". ;(

And when I try to create a new one, it performes an illegal operation. ;(

You need to update half life to version 1.1.1.0 and make sure you've got beta 1.0 of ESF installed before connecting.
