Adblock Plus issue

Now, I've been using Adblock Plus -no other blocking extensions- for for almost a year now, and love it. My issue is that it has been going totally blank, including all my personal addresses & filters, as if disabling itself every few weeks or so. And my subscriptions are always current and up-to-date. Any one else having this same issue, and/or have a solution? I really don't want to use another extension if I don't have to.
