Anyone else had this problem with Clickbank?

I've been doing fine now. I'd been averaging about $100 a day mailing CB offers. Last CB week, I had my first $1000 week. Then, since Wednesday, I've had 0 sales. The hops have been normal, so traffic hasn't changed. Same list and all. However, the only income I've made this week has been from recurring.

Something seems fishy.
