[L4D2] I get an error Please help me.
 

I've applied promod sky.


sm_cvar sv_allow_lobby_connect_only 1

When this command is applied, the server can not be connected.

Server error - failed to handle reservation request.
BinkOpen( h:\program files (x86)\steam\steamapps\common\left 4 dead 2\left4dead2\media\l4d2_background05.bik )



Is there a workaround?

sm_cvar sv_allow_lobby_connect_only 1
I do not want to change this cheat
