Having the same problem, just wanted to add my voice.
Basically the same exact situation as Casa, except I haven't had support delete my old user and API yet.
Had an API for Askimet, deactivate that plugin and the API for the upgrade to 2.5, but apparently there is more tied to my external website than just the API key.
Amusing, having a warning telling you not to use your own API key...
I'll keep an eye on this thread for a solution to the non-existent 'access list' problem.
Looks like the WP login system didn't accept my password anymore, the account was tied to an out of date email address, so I figured I'd just get a new API + account and it would be easy peasy...boy was I wrong. And to boot when I created my new account the system accepted my KeePass-generated password during account creation, and then didn't accept it during login...nice!
Is there a REASON this is SO DIFFICULT?
"Please delete my account
We don’t. Don’t worry about unused accounts. It doesn’t hurt anything.
The software could break if we deleted accounts, so accounts are permanent."
I can't even keep straight what site I'm on, what login I should be using, how to find my way from my dashboard to help docs to the forums back to this post, back to my profile (which one am I looking at again)...what a damn mess...reminds me of account management over at EA.com...
No, seriously. If I want my account deleted, you should delete it. It //obviously// sometimes DOES hurt something. And if the software breaks because you delete the accounts, fire your programmers.
How does one contact WordPress support? They seem to have made that extremely difficult.
Sorry if I come across as incredibly annoyed, something about wasting two hours trying to figure out a mess caused by one bit of short-sightedness after another has this effect on me...
