[File dayz_server.pbo not signed by acceptable key to play on this server]

I am trying to run the 1051 version. I tried adding the 1042 bikey and it gave me several more errors messages with other files addons not having an acceptable signature.. So took it out again and now back to the same not acceptable key.

Yes I have the dayz_epoch1051.bikey is in the server keys folder (however the bikey that is in the folder was obtained from the client files which I read something in the readme file that said to use it for server since no server bikey was made). Yes I am using only the epoch mod and all other map keys are in the keys folder too. I started out with only the one map that I was going to use with the key in the server keys folder but received several error messages and then added them back along with the files associated with the maps. After the addition of the files and bikeys all other messages no longer appeared but the epoch_server.pbo key message is the only one I am receiving.

  The only dayz_epoch.bikey that is in the keys folder in the 1051. Could it be that I need the earlier dayz_epoch1042.bikey in the folder too? I removed that bikey after receiving the messages saying the server was not running the same update as my client files. That took care of the both client and server running the same version.

I need some help with getting my epoch server running. I have already fixed several errors but now I am receiving the following error message. "File dayz_server.pbo is not signed by an acceptable key to play on this server, remove listed files or install additional acceptable keys."

  I have already downloaded the server files again and replaced them, however I am still receiving the error message. Would someone help me to either fix the error or point me in the right direction to get an acceptable key so I can get my server running?
