Error: server failed to transmit file 'maps

[3nf]

hi my problem is with hlbeta, when I switch to a new map, players can not enter because they say this error

 

Server # 3

Couldn't find map maps/ba_jail_rofl_v2.bsp, server will download the map

Error: server failed to transmit file 'maps/ba_jail_rofl_v2.bsp'

Error: could not load file maps/ba_jail_rofl_v2.bsp

Model maps/ba_jail_rofl_v2.bsp not found and not available from server

Cannot continue without model maps/ba_jail_rofl_v2.bsp, disconnect

 

 

and if you start a server other than hlbeta, the map is downloaded perfectly,

 

 

 

thanks for your help
