[wp-polls error] With wp 2.5

Hi. I was using wp 2.3.3 with wp-polls and everything was perfect. Now, after the upgrade to 2.5, the plugin gives some errors when i try adding a poll:

Error In Adding Poll ‘How old are you?’.

Error In Adding Poll’s Answer ‘0-18’.

Error In Adding Poll’s Answer ’18’.

Error In Adding Poll’s Answer ’18-35′.

Error In Adding Poll’s Answer ’35-120′.

Anyone can help?
