Key accept error

[grandfalen 0]

Whenever i try to join a server for dayz origins mod i get this error: (im using playsix)

Files "C:\User\Administrator\Documents\arma2\@3lb_f22\ad dons\3lb_f22.pbo", "C:\User\Administrator\Documents\arma2\@GLT_Missle Box\addons\glt_misslebox.pbo", "C:\User\Administrator\Documents\arma2\@GLT_Missle Box\addons\glt_misslebox_config.pbo", "C:\User\Administrator\Documents\arma2\@CBA_CO\add ons\cba_ai.pbo", "C:\User\Administrator\Documents\arma2\@CBA_CO\add ons\cba_arrays.pbo", "C:\User\Administrator\Documents\arma2\@CBA_CO\add ons\cba_common.pbo", ... are not signed by a key accepted by this server. To play on this server, remove listed files or install additional accepted keys.

This happens everytime i join any server. If anyone can help me fix this problem please let me know as soon as possible. Thank you. (i didnt know how to post a picture and when i tried i got an error. Sorry, but thats the error word for word.)

check what expansions you are running as its trying to join with 3 other mod folders enabled.

check the custom launch parameters

Alright grandfalen what you wanna do is you see that switch/button thats switchs from multiplayer to singleplayer? Click it over to Singleplayer and launch the game. Now join a server from there. P.S. Type under filter name section "Origins"
