need help battlefield

[SemperFi]

i dont kno what happeend to my battlefield vietnam. i tried to find a way to get punkbuster to work but then i realized it wont work because i hadnt installed it when i first installed bf vietnam.

 

so i go to uninstall bf vietnam and i get an error of some sort and then it tries to install bf vietnam again. i made sure i clicked punkbuster this time but when i clicked the next button to install it it didnt do anything

 

so i said forget uninstalling it ill just play on servers that dont need punkbuster. i try to join a server and it says invalid cd key everytime. i figured maybe there mite be something wrong with the cd so i tried a new one and still no luck.

 

i deleted the battlefield vietnam folder hoping it would then let me install it but still no luck. went to add/remove programs and its not listed.

 

i have no clue what to do and i really love this game
