And I'm back again. Would someone be kind enough to provide the IP for the new authentication/login server, please? I need it for my .bat workaround to work!
Edit: Ah, of course the auth server IP is in the .xml, which I can access no problem in a browser. Got things working again!
Tequila still won't get past the WebClient error. If I perform a fresh install from another location (eg., download the new .exe to E:\, and then direct Tequila to E:/City of Heroes), it hangs on "fetching manifest" and never progresses.
Another oddity I noticed is that the original Tequila.exe deletes itself when installing (a Tequila.exe is then created in the chosen install location). Not sure if that's intended behaviour.
I've tried all of the steps in Silk's guide. I wonder if there's some Windows service/feature that needs to be enabled for Tequila to function fully?
