"Blah blah blah", hey? Sounds like you've got a bad case there.
The same Chi password applies whichever computer you sign in from. If you can't sign in from work, but you can from home, I'd say you're using different passwords. If you're signing in automatically, without actually typing in a password, maybe you've forgotten what the password is. Anyhow, you can change the password to make sure you know what it is.
You can re-set the password by clicking where it says "Forgot your password? Click here", but you'll need access to your email to make the new password active. If you can't get to your email from work, you might as well wait till you get home, and then change your password there. If you're signed in, you can change the password on your profile (by pressing the "Details" button under your name), but you still need to know your current password. If that isn't what you thought it is, you'll have to sign out and then click on the "Forgot your password" link.
Confused? I hope not. Let us know how you get on.
