Hello!

Multiplayer is currently being overhauled for Supernova, and not available at this time. However, custom race generation should be functional when you click new game, could you provide a screenshot?

Hey, yes, as mentioned by Ramma, Multiplayer is supposed to be grayed out.
While the generate button not.

In order to use generate button, you need to have internet connection.
Are you on steam or epic?

It's turned off in Supernova - they're working on improvements.  It'll be back soon - we hope   

The "Generate" button on the create custom Civ should not be greyed out.  I just checked and it's working for me in both "Supernova" and "Supernova - Insiders Edition".  Did you try verifying your files?

I have verified files and it still says "user not authenticated". I tried the original game, and I have multiplayer there, but the metaverse and mod manager is greyed out. Should that be the case?

Hey, please let me know if this issue has resolved with the new Insider Build update

How to opt-into a specific build:

On Steam:

• Select "Galactic Civilizations IV: Supernova in your Steam Library list.
  
• Right-click and select Properties.
• Select the BETAS tab.
• From the dropdown, select the desired build (Insiders) and exit the dialog.
• Steam should pull down the changed files; if you ever want to go back, do the same as above but select
  default (or None).
  
  

On Epic For Insider Build:

To enable the patch, please do the following:

• Open the Epic Launcher
• Select "Galactic Civilizations IV: Supernova - Insider's Edition"/ TEST Edition
• Install and play!

I still cant get this working. Tried unblocking Epic in firewall but its still greyed out. 

Try emailing support@stardock.com

That's worked for me in the past.

No I still have the problems described. is there some files I can send so you can check whats wrong?

We've been working on the support ticket for this lately, and released a new Insider build update, think it should resolve this, can you confirm? If not please send over a save file or relevant files via dropbox link

I still need help with this. latest release still shows access denied.
