You're using a different version to the server, your files must match including the beta-patch.

Get the correct files :)

Your error messages are telling you that you're trying to use standard Taviana files and they're for normal Taviana, you're wanting Epoch Taviana so you need the correct files from http://dayzepoch.com/wiki/index.php/Taviana_1.0 and change your launch parameters to :

-mod=@DayZ_Epoch;@Tavi_DayZ_Epoch
