LaunchHostCorrection w/good password?! Mac

Shaman

New Email
OK...Yahoo works beautifully all the time on my main account that I've had for years. But on my new accounts, and only on my Mac, I get this message whenever I try to sign in:

Ouch!
The error, LaunchHostCorrection, occurred when trying to connect to Yahoo! Mail.

It seems totally bizzarre and random...why should I be able to sign in on one account and not the other, or be able to on my PC, but not my Mac? And it's not my password... I triple checked that. Please help! Thanks
