Just found an old copy of AA Overmatch and I made an account, when I try to log in it says "Your internet connection may be down or the authorization server may be undergoing maintenance", is there any way to fix this or go around it?
Hey, as the official auth servers shutdown some time ago you'll need to register a 25Assist account and download the client in order to download a copy of the game that will work with Assist.
If you haven't already done so, you can register an Assist (game) account
here.
After doing so, sign into the client to begin the activation process. Once your account has been activated and you're signed into the client, the game will download via the client and you'll be able to connect to a game server.
