Call of Duty 4 Multiplayer Not Working Help!!!

[AvengedNightmare100]

I have just bought CoD 4 for my ps3 and i done the 1.40 ( i think that is the latest one) patch, i then clicked onto Multiplayer and it came up for the menu as if to choose to play online or split screen, chose online and then it done the usual loading data bit then just reverted me back to my ps3 home screen, i think that they have maybe shut down the servers can anyone help me please

Mine is doing the same thing. I haven't been able to play online for months. Single player works fine but as soon as I chose online, the whole game quits to the PS3 screen. All of my other COD games are still playable online but COD4 keeps crashing. Please advise!
