Kicked from server

[shakes53 0]

I followed this guide:

http://kodabar.blogspot.dk/2012/05/how-to-install-dayz-with-arma-2-free.html

I did everything else but make shortcuts and just used six launcher to join a server. I verified my game and all is well.

when I click join in six launcher it tells me "No entry 'bin\config.bin\CfgVehicles\'"

they say to ignore that and I click continue and it send me to the menu.

then I try to join a server manually and it tells me "kicked from the server"

"...are not signed by a key accepted by this server. To play on this server remove the listed files or install additional accepted keys"

i'm using arma II free and a valid bought operation arrowhead key/game from gamestop

and it says at menu top right

ArmaII free

beta
