Problem with CBA during connexion to server

Hi, when I want to connect to my server I receive this message :

Files :

• cba_a2_main.pbo
  
• cba_a2_xeh
  
• cba_arrays.pbo
  
• cba_common.pbo
  
• cbadiagnostic.pbo
  

are not signed by a key accepted by this server. To play on this server, delete files above or install additional accepted keys.

(Translation from french, it may be not accurate)

In my local @CBA folder I have the directory 'Addons' containing .pbo and .bisign. And I have the folder 'Keys' with the .bikey.

It's the same thing on the server.

P.S : I have not the last version of CBA, I don't want install the latest because it requires a beta patch.

Can you help me ?

Thank you.

EDIT : If I download and install the latest beta patch, should I download the latest version of the server (v1.63) or can I keep the v1.62 ? (I have downloaded the v1.62 for the server because my game runs on the v1.62)

I think I have solved the problem.

I have put all the .bikey on my server in the main 'Keys' folder.

I say 'think' because I can't check if it works, when I want to connect to my server, I receive the message "You have been banned". WTF ?! :eek:

I hope it's not my CD key which has been banned...

I have tried to connected many times to my server, it may cause the message. Isn't it ? :(

On my server I have the file ban.txt containing a number : "756678".

I delete the file ? What am I suppose to do ?

Just remove the entry in your bans.txt file (the number.. this is your Arma2 GUID) and restart your server you should be able to join again.

Ok thank you

EDIT : My first problem is solved. Indeed, all the .bikey have to be in the main directory 'KEYS'.
