Aye as above , although I never put in my jacket when I join ,some of the guys say it doesn't connect with out you doing it .
1/ log into AA
2/ Press ESC
3/ Blank screen with logo there press TAB
4/ Type open 69.25.19.14
5/ Sit back and watch for nades
Useful tip is , if the server says its full , click cancel , then TAB , the the UP arrow , and your last command is there , then pres enter again
some problems are caused by either not having punkbuster enabled on the DEPLOYMENT screen
or not have the latest version of punkbuster
Above all make sure you do your basic training
