Hotmail: not checked

For reasons unknown X-notifier is no longer checking my hotmail messages. If I click on the box it takes me to my hotmail webpage and shows my messages but it will not check my messages as it used to, showing the number of unread messages (even if I right-click and press the Check Now button it states Hotmail: not checked).

I've uninstalled and reinstalled X-notifier and deleted and reinstalled my hotmail account, however, it still will not check my emails.

Any thoughts?
