I click authenticate, it loads and then nothing happens.
I tried cross save yesterday it had a lot of issues so im trying now today and it still wont authenticate any of my accounts. i tried what other people tell me worked for them, but it still doesn't work for me. when i click authenticate for blizzard or steam it brings me to another window telling me to login to blizzard/steam i click log in, it loads for a second or two then absolutely nothing happens, like i never hit a authenticate button or anything, i keep repeating that for a day now i try every couple hours still nothing.
You say you've tried what other people have said, so just to make sure that you've done the following:
Tried different browsers, both normally and in privacy mode
Tried clearing your cache/cookies
Insured that you don't have adblock or popup blockers enabled on said browsers when trying the above.
If you've not tried one of the above, definitely try it; if it still doesn't work, please respond back so we know you still have the issue.
