Clear / Delete Poll results stopped working

[Mark Godfrey]

I used to clear out old results with 

curl -X DELETE --user xxx:xxx -H "Content-Type: application/json" -H "Accept: application/json"  "http://api.polleverywhere.com/multiple_choice_polls/IU68fUaUjy58yWS/results.json"

Which no longer works. I tried the equivalent in Fiddler,and I get a 401 in response. i have tried with and without .json extension,

Am i not allowed to delete the poll results anymore?!

This is different to wrong/unauth headers which get redirect to login page.

Halp!?
