Re: Cannot log into member login and it will not let me play sims 3
@wiktorgris The password you need to use is the same one you use to sign into Origin or any EA site, so try that. But if your password contains special characters, that may explain the issue: the launcher doesn't accept certain characters, for example ! or &.
For the connecting error, open Applications > Utilities, launch Keychain Access, write sims in the search bar, and delete any entries with sims3 in the name. This should clear the active login and stop the game from automatically attempting to connect.
