Council of Elrond

System: Windows XP

No matter what I delete or try, Subversion simply will not ask me for a user name and password, instead automatically using the generic password.

In other words, I can't persuade the program to let me attempt to enter a more permissive user name and password.

Does anybody know what the heck I'm supposed to do?

I have tried:
Deleting the /auth folder.
Changing where the the folder's url, then changing it back again.
Deleting the folder and creating a new one with the checkout url.
Uninstalling and reinstalling Subversion.

Any other ideas?

I managed to do it for the "Metw" folder, but I still can't commit anything to "core"; it's giving me a Forbidden error.
