I am here to save the day JohnStamosJR.
Here we go:
First off, make sure you know what version of RtCW you have. To find out, simply launch multiplayer, and open the console. You should see the version in the bottom right of the console. (1.0 or 1.4) You SHOULD have 1.41
Next step:
Follow this link -

If you have version 1.4, click the link that says
"RtCW 1.4 PunkBuster Fix"
This will download an installation file. Once you've downloaded it, you will run it! It will ask you to browse for your RtCW directory. You must click browse and then look through your computer folders to find where Return to Castle Wolfenstein is installed.
If you bought RtCW on steam, it should be located in (C:/Program Files(x86)/Steam/SteamApps/common/Return to Castle Wolfenstein)
Click on the 'Return to Castle Wolfenstein' folder, hit okay, and click install. The program will then install necessary files, and update PunkBuster. Once it is done just hit okay or finish (whatever it says) and then you are done!
NOTE: When you launch multiplayer and look at the server list, you MUST click 'Get new server list' to generate the servers. But only so this once, you won't have to do it again.
ALSO NOTE: There is only 1 server left where real people play, and that server is called 'ECGN Network 24/7 Beach'. If you need anymore help, feel free to message my inbox.
I'll see you on the beach!
