Changing personal URL Bug?

Hi, I've tried to change my facebook personal URL (business page) by going to facebook.com/username. I've got 25+ likes and when I try to change it, it shows
"Loading" and stops there...

My goal is to modify the homepage URL :
[You must be registered and logged in to see this link.] name]/12345623452"
to
[You must be registered and logged in to see this link.] name]

*where page name is the business name.

Anyone knows how to fix this?
Thanks

It seems to be a known bug, I've seen another 2 members here complaining about the same thing. You can report this bug [You must be registered and logged in to see this link.] (form) and in the [You must be registered and logged in to see this link.]
