I can login to Pokemon Gold but can't login to pokemon silver and i don't know much about the merge, do i have to do anything in order to login to pokemon silver? I had an account on red server btw.

Actually the Red server is no longer existing, nor is the Yellow server really.

 

What happened is Red and Blue server are merged into one only Silver Server, and the Yellow Server is becoming Gold Server.

 

You should be able to connect you after you download the new client of the merging thing : Download link : https://pokemonrevolution.net/download.php

 

Please note that Silver Server is for now down and that you have to connect on the website to proceed to the merge of your Blue and Red account. Be sure to click the RED account when it is asked which was your main so you wont lost any data of yours :)

 

PS : Actually the merging tool is put down too to avoid more bugs to players :) Please have a bit of patience and everything is gonna be alright :D

 

Of course nobody's account going to be deleted but be careful to fully understand the merging thing when you'll have to do it :)
