Arma 3 Exile Error "session lost - verifying pbo failed: @exile\addon\exile_client.pbo" and more.

Hi iv'e been trying to create an Arma 3 Exile Server on Altis, From a fresh install apart from setting the server name and join password i recieve either "session lost - verifying pbo failed: @exile\addon\exile_client.pbo" on connecting or im stuck in the grass unable to move or press any button then put back onto the server select option, I've tried countless reinstalls as well as redownloading the exile mod, Can you help please?

Nvm ive fixed it, not sure how to close this .

I removed the @Epoch folder from the server, Copied mine from steam and put it on the server, Changed the Additional mod section to match the @EpochMod, and disabled the key checking on mods in the config file, hope this makes sense!
