i cant get onto the private server but I have the beta

Which version of Dalek Mod are you using? The private server uses the absolute latest version available, which is cureently U46.

I'm using the latest

*U46. 2

 you need to login in the game if you haven't already
if you have logged in your SWD account in the game then I really dunno what's the issue 

ive logged in and out but it wont let me still

Can you show the error you getting?
