I have try this "C:\Users\[username]\AppData\Local\PunkBuster\ET" or somewhere near but no et-key at all
There is my legacy key if i understand right. If you install Legacy.
I don't think that key is something that save XP ore any other things if you play on Bunker but not shore.
On a normal install Windows XP C:Wolfenstein - Enemy Territory/and so on, Win 7 C:Program (X86)/and so on, If you place
it on another HD then operate system like D: you can put ET installation direct under the disk like Windows XP.'
If you find some of this and you have any off this system you should put it like Old Chap say.
- place it in the etmain folder - NOT NQ
Can be good to go to a server also. B10 still have PB on so go there and DL what is needed.
If you play Nitmode you also have another key but that you lost if you did not also save it. This is under Nitmod folder named nkey.
This is how the key locks (placed) at me but i don't know if its is the right way.
Good luck and Happy Easter
