I have been working on a campaign for a while now, just setup stuff so far, but today it won't let me sign in as a GM. I tried using a different browser, I made a new accound and signed in just fine, but when i promoted it to GM and tried again, it would get stuck on the black loading screen. I even had my other players try to get in as GMs but they couldn't. I know it's just this campaign because I made a new campaign and it started up fine. I really need some help as I have put a lot of work into this campaign.
