Adblock Plus

I'm using AdBlock Plus 0.7.5.1, and I have following filter subscriptions:
- EasyElement+EasyList
- ABP Tracking Filter
- Fanboy's list
- JamiePlucinski.com

Topic name explains what the problem is about. I found my subscriptions deleted 2x or 3x. The only thing I noticed about this event is that it happens suddenly: it works normally, and then suddenly further opened tabs aren't ad-blocked...

I wasn't able to notice what triggers the deletion...

Anyone having the same problem?

I wouldn't recommend having all 3 lists running at the same time, so many double-up's used by all the adblock lists... which would slow your web browsing down.
