It's not so much that I can't log in to CIT (although I can't). It's the message I get when I try to log in.
Instead of telling me that the password is invalid or whatever (and it shouldn't be, since there was a cookie remembering the PW for me), it tells me:
"Username or Password were not supplied. Please try again."
In fact, it says this when I first open the CIT page before I enter anything, which seems odd. If I change my PW slightly, I get the standard "invalid password" message.
My own experience was:
1) Last night I couldn't log into CIT so I clicked on "trouble logging in" and got a new PW.
2) I logged in with new PW and immediately changed it back to old PW. Still can't log into CIT.
3) Tonight, when problem still persisted, checked forums for solutions.
3a. Able to log into forum (obviously).
3b. Cleared cache repeatedly, but can't log into CIT.
3c. I AM able to log in normally in an InPrivate window but not normal window.
Also, it does seem odd that several people are having issues with cookies since the cleared badge data a few days ago.
Added later:
I tried the "trouble logging in" link a second time. I wanted to see if the new PW would allow me to see my character list (the first time I immediately changed the PW). I can log into the forums with my original PW but not CIT or Titan Home (to change my PW back) with either password.
