I haven't been on this game since 2017 and a lot has changed since then including the servers which used to be three (blue, red and yellow) whereas now there only are two (silver and gold). I downloaded the latest version and entered my account details but I wasn't able to join the silver server and the gold server only loaded my old yellow server save but I would rather have my blue server save over the yellow if I had to choose one.

Any way I can get my old blue server save back? Also, why can't I join the silver server?

Hello there @Simzon. Welcome back.

 

Some small insight on what happend over the past few years, Red and Blue server merged to become the now Silver server and Yellow was renamed Gold. If you cannot access Silver server you would need to Merge on your dashboard which can be accessed from here.

 

Once this is done after you have merged try logging in, if it still gives you the error of "Incorrect username or password" reset your password, do note this should be done after merge and not before or during, it can be reset from here.

 

For more info about the merge and about the errors that might occur with it (I hope not), take a look here.

 

Once again welcome back and Good luck.
